Hi I am building a dataset, but the data I am merging is in different formats.
From the Excel sheet i import its in numeric 8, and the other 2 datasets im merging to are character 20, so I want to change the numeric 8 to char 20.
How can I change the variable acctnum, to char 20? (I also want to keep this as its name, as I presume a new variable will be created)
data WORK.T82APR;
set WORK.T82APR;
rename F1 = acctnum f2 = tariff;
run;
proc contents data=T82APR;
run;
While this thread is already dead, I thought I'd way in and answer why the 14 digits conversion became in E notation.
Typically, or rather, unless otherwise specified, numeric formats in SAS use BEST12 format. As such, when a numeric value is longer than 12 characters (including any commas and periods), BEST12 chooses E notation as the best way to format the value.
The input function, in that case receives the formatted value put(acctnum, BEST12.). There would've been 2 ways around it.
Either use
input(put(acctnum, 14.), $20.);
Or, change the format of the variable using the format statement (directly in a data step or with proc datasets like) - this has the added benefit that if you open the table in SAS, you will see the 14 digits and not the scientific formatted value.
proc datasets library=work nolist;
modify dsname;
format acctnum 14.;
run;

Try this:
data WORK.T82APR ;
set WORK.T82APR;
acctnum = put(F1, $20.);
rename f2 = tariff;
run;
Ok, I didn't pay attention to your own rename statement, so I adjusted my answer to reflect that now.

Hello,
I am analyzing the next dataset with this information .
The column ['program_number'] is an object but I want to change it to a integer colum.
I have tried to replace some values but it doesn´t work.
as you can see, some values like 6 is duplicate. like '6 ' and 6.
How can I resolve it? Many thanks
UPDATE
Didn't see 1X and 3X at first.
If you need those numbers and just want to remove the X then:
df["Program"] = df["Program"].str.strip(" X").astype(int)
If there is data in the column which aren't numbers or which shouldn't be converted, you can use pd.to_numeric with errors='corece'. If there are cells which can't be converted, you'll get NaN. Be aware that this will result in floating numbers.
df["Program"] = pd.to_numeric(df["Program"], errors="coerce")

You want to use str.strip() here, rather than replace.
Try this:
df1['program_number'] = df1['program_number'].str.strip().astype(int)
I'm trying to convert a character variable to a numeric variable, but unfortunately i'm really struggeling. Help would be appreciated!
I keep getting the following error: 'Invalid argument to function INPUT at line 3259 column 17'
Syntax:
Data want;
Set have;
Dosis_num = input(Dosis, best12.);
run;
I have also tried multiplying the variable by 1. This doesnt work either.
The variable looks like this:
Dosis
155
201
2.1
0.8
123.80
12.0
3333.4
00.6
Want:
Dosis_num
155.0
201.0
2.1
0.8
123.8
12.0
333.4
0.6
Thanks alot!
The code will work with the data you show. So either the values in the character variable are not what you think or you are not using the right variable name for the variable.
The code is trying to only use the first 12 bytes of the character variable. Normally you don't need to restrict the number of characters you ask the INPUT() function to use. In fact the INPUT() function does not care if the width of the informat used is larger than the length of the string being read. So just use 32. as the informat since 32 is the maximum width that the normal numeric informat can read. Note that BEST is the name of a FORMAT, if you use it as the name of informat it is just an alias for the normal numeric informat.
If the variable has a length longer than 12 then perhaps there are leading spaces in the variable (note the ODS output displays do not properly display leading spaces) then use the LEFT() function to remove them.
Dosis_num = input(left(Dosis), 32.);
The typical thing to do here is to find out what's actually in the character variable. There is likely something in there that is causing the issue.
Try this:
data have;
input #1 Dosis $8.;
datalines;
155
201
2.1
0.8
123.80
12.0
3333.4
00.6

All those 2020202020 are spaces, which should be there (all strings are space-padded to full length). Period/Decimal Point is 2E, Digits are 3x where x is the digit (because the ASCII for 0 is 30, not because of any other reason). So for example for the last one, 00.6, 30 means zero, 30 means zero, 2E means period, and 36 means 6.
Check to make sure that you don't have any other characters other than digits (3x) and period (2e) and space (20).
The other thing to verify is that your system is set to use . as the decimal separator and not , as many European systems are - otherwise this requires the commaw. informat. You can actually just try the commaw. informat (comma12. is sufficient if 12 is plenty - and don't include anything after the period) as anything that 12. can read in also can be read in by commaw..
I need to output lots of different datasets to different text files. The datasets share some common variables that need to be output but also have quite a lot of different ones. I have loaded these different ones into a macro variable separated by blanks so that I can macroize this.
So I created a macro which loops over the datasets and outputs each into a different text file.
For this purpose, I used a put statement inside a data step. The PUT statement looks like this:
PUT (all the common variables shared by all the datasets), (macro variable containing all the dataset-specific variables);
E.g.:
%MACRO OUTPUT();
%DO N=1 %TO &TABLES_COUNT;
DATA _NULL_;
SET &&TABLE&N;
FILE 'PATH/&&TABLE&N..txt';
PUT a b c d "&vars";
RUN;
%END;
%MEND OUTPUT;
Where &vars is the macro variable containing all the variables needed for outputting for a dataset in the current loop.
Which gets resolved, for example, to:
PUT a b c d special1 special2 special5 ... special329;
Now the problem is, the quoted string can only be 262 characters long. And some of my datasets I am trying to output have so many variables to be output that this macro variable which is a quoted string and holds all those variables will be much longer than that. Is there any other way how I can do this?
Do not include quotes around the list of variable names.
put a b c d &vars ;
There should not be any limit to the number of variables you can output, but if the length of the output line gets too long SAS will wrap to a new line. The default line length is currently 32,767 (but older versions of SAS use 256 as the default line length). You can actually set that much higher if you want. So you could use 1,000,000 for example. The upper limit probably depends on your operating system.
FILE "PATH/&&TABLE&N..txt" lrecl=1000000 ;
If you just want to make sure that the common variables appear at the front (that is you are not excluding any of the variables) then perhaps you don't need the list of variables for each table at all.
DATA _NULL_;
retain a b c d ;
SET &&TABLE&N;
FILE "&PATH/&&TABLE&N..txt" lrecl=1000000;
put (_all_) (+0) ;
RUN;
I would tackle this but having 1 put statement per variable. Use the # modifier so that you don't get a new line.
For example:
data test;
a=1;
b=2;
c=3;
output;
output;
run;
data _null_;
set test;
put a #;
put b #;
put c #;
put;
run;
Outputs this to the log:
800 data _null_;
801 set test;
802 put a #;
803 put b #;
804 put c #;
805 put;
806 run;
1 2 3
1 2 3
NOTE: There were 2 observations read from the data set WORK.TEST.
NOTE: DATA statement used (Total process time):
real time 0.07 seconds
cpu time 0.03 seconds
So modify your macro to loop through the two sets of values using this syntax.
Not sure why you're talking about quoted strings: you would not quote the &vars argument.
put a b c d &vars;
not
put a b c d "&vars";
There's a limit there, but it's much higher (64k).
That said, I would do this in a data driven fashion with CALL EXECUTE. This is pretty simple and does it all in one step, assuming you can easily determine which datasets to output from the dictionary tables in a WHERE statement. This has a limitation of 32kiB total, though if you're actually going to go over that you can work around it very easily (you can separate out various bits into multiple calls, and even structure the call so that if the callstr hits 32000 long you issue a call execute with it and then continue).
This avoids having to manage a bunch of large macro variables (your &VAR will really be &&VAR&N and will be many large macro variables).
data test;
length vars callstr $32767;
do _n_ = 1 by 1 until (last.memname);
set sashelp.vcolumn;
where memname in ('CLASS','CARS');
by libname memname;
vars = catx(' ',vars,name);
end;
callstr = catx(' ',
'data _null_;',
'set',cats(libname,'.',memname),';',
'file',cats('"c:\temp\',memname,'.txt"'),';',
'put',vars,';',
'run;');
call execute(callstr);
run;
I would like to create a new variable in SAS which takes the value 1 if an observation in the variable "TEXT" contains 8 numbers. The problem is, that TEXT is a character variable. Is it possible to make some kind of a format search in SAS?
I assume by '8 numbers' you actually mean 8 digits. For 8 separate numbers, that would be different.
So something like the code below might help.
The modifier 'kd' meaning KEEP DIGITS in COMPRESS function does the magic here:
data indata;
length TEXT $20;
input TEXT;
datalines;
a
123
12345678
A12345678
;
run;
data outdata;
set indata;
length TEXT_DIGITS $20 _8_DIGIT_INDICATOR 3;
TEXT_DIGITS = compress(TEXT, , 'kd');
if length(TEXT_DIGITS)=8 then _8_DIGIT_INDICATOR = 1;
run;
Adjust the logic as you need - e.g. if no other character in input value is allowed or something else.
Also functions like ANYDIGIT, NOTDIGIT might be useful.
I've found two parameters defined like these:
&TM_PERIOD+4&/&TM_PERIOD(4)&
It's to pass data from a database to a form.
If the format of the data would be DDMMYYYY what are differences between those two parameters?
if TM_PRIOD is in form of DDMMYYYY then
TM_PERIOD(4) equals DDMM
TM_PERIOD+4 equals YYYY
the (4) means 4 characters
the +4 means after the 4th character
TM_PERIOD+1(2) = DM
(2 characters after the first)
These are not bit operations. +n specifies a string offset and (n) specifies the length.
They can be used independently of each other as well, so you can use just +n or just (n).
So:
data: lv_text(20) type c.
lv_text = "Hello".
write: / lv_text+2(3).
would output 'llo', for example.
