The org-mode tutorial often talks about setting the value of a variable to change the behavior of the mode. For example, in this org-mode tutorial:
This warning is deactivated if the task gets scheduled and you set org-agenda-skip-deadline-prewarning-if-scheduled to t.
I have been searching for a while but it looks like knowing how to set an emacs variable value is an assumed knowledge in many tutorials.
Could someone please educate me how and where to set variables in the org-mode? Is it set in the .emacs file or in each org file? Do these questions even make sense or am I missing some important concepts?
Thank you very much!
With Customize
If you want some help about a variable, you can use C-h v then Emacs will ask you the variable name.
There if you enter org-agenda-skip-deadline-prewarning-if-scheduled you will see a buffer with the variable
description. At the end you will see a clickable customize. Click it and you will see an interactive buffer from which you can change variable value (saved in your .emacs file).
Note: you can directly use M-x customize-option + variable name
With setq lisp function:
Another way is to directly use this:
(setq org-agenda-skip-deadline-prewarning-if-scheduled t)
in your .emacs file or
in the *scratch* buffer, then M-x eval-buffer
(Your modification is immediate but not saved.)

I've created a model with Uppaal in which several integer variables change over the course of time. Now I would like to save the values of the variables during the modelling process somewhere (best in xml or a text file). In the Uppaal documentation (https://www.it.uu.se/research/group/darts/uppaal/documentation.shtml) I found the method in point 13 (How do I export and interpret the traces from Uppaal?) and tried the Java API way already, in the hope that it can output the variables as well as the traces. Unfortunately this method seems to be limited to traces. Does anyone know a method to save the variable values from Uppaal?
Hopeful greetings,

Solution from the comments.
to export the variable value tractory over time, one may use SMC query in the verifier.
For example:
Typeset the following query: simulate 1 [<=300] { Gate.len }
Click Check
Right-click on the query, and from the popup menu choose Simulations (1)
Observe a new window popup with a plot
Right-click on the plot and choose Export Comma Separated Values
Follow the save file dialog and observe the resulting file to contain time and value sequence.
Note that SMC assumes that all channels are broadcast and there are no deadlocks.
I looked at a code by someone previously and saw them do code that went like:
set Today=%DATE:~0,3%
And if the variable (%DATE%) was executed (echo %DATE%) it would come out with the first 3 letters of the date it was, this worked for other commands such as %TIME%, etc... But I was wondering if it was possible to specify what it takes instead of a first section, the reason I want this is cause I am attempting to make a logging system that logs with the times and date, though the %time% variable consists of colons, which can't be put as folder names,
Some attempts:
set Today=%TIME:~0,2 ~4,5%
set Today=%TIME:~0,2:4,5%
The list goes on, so to specify in more detail what I want, it is simply a way to take only the numbers of the %time% variable, or to remove the colons with a filtering method, if either are possible or you have a suggestion, please go ahead and tell me.
Thanks for reading. :)
You can't specify multiple regions from the variable but it is very easy to accomplish what you want:
set Today=%TIME:~0,2%%TIME:~3,2%
I assume you see the pattern...
Remember that DATE and TIME might look different on different locals so this may work fine on your local system but not if you go to a different system or change your local settings!

I have a file variable in d3 pick basic and I am trying to figure out what file it corresponds to.
I tried the obvious thing which was to say:
print f *suppose the file variable's name is f in this case
but that didn't work, because:
SELECTION: 58[B34] in program "FILEPRINTER", Line 7: File variable used
where string expression expected.
I also tried things like:
list f *didn't compile
execute list dict f *same error
execute list f *same error
but those also did not work.
In case any one is wondering, the reason I am trying to do this in the first place is that there is a global variable that is passed up and down in the code base I am working with, but I can't find where the global variable gets its value from.
That file pointer variable is called a "file descriptor". You can't get any information from it.
You can use the file-of-files to log Write events, and after a Write is performed by the code, check to see what file was updated. The details for doing this would be a bit cumbersome. You really should rely on the Value-Add Reseller or contract with competent assistance for this.
If this is not a live end-user system, you can also modify an item getting written with some very unique text like "WHAT!FILE!IS!THIS?". Then you can do a Search-System command to search the entire account (or system) to find that text. See docs for proper use of that command.
This is probably the best option... Inject the following:
IF #USER = "CRISZ" THEN ; * substitute your user ID
READU FOO FROM F,"BLAH" ELSE
DEBUG
RELEASE F,"BLAH"
END
END
That code will stop only for one person - for everyone else it will flow as normal. When it does stop, use the LIST-LOCKS command to see which file has a read lock for item "BLAH". That's your file! Don't forget to remove and recompile the code. Note that recompiling code while users are actively using it results in aborts. It's best to do this kind of thing after hours or on a test system.
If you can't modify the code like that, diagnostics like this can be difficult. If the above suggestions don't help, I think this challenge might be beyond your personal level of experience yet and recommend you get some help.
If suggestion here Does help, please flag this as the answer. :)
I'm new to Selenium IDE. Right now I'm trying to store the filepath/URL of an image on a webpage, and then verify that the filepath/filename follows a set of filename conventions.
The progress so far:
I've installed a user extension that allows me to use a command called "storeImagePath". I can store the filepath/filename of the image and save it as a variable called imagePath.
What I'm stuck on:
I can echo ${imagePath} and it's giving me the correct filepath, but I don't know how to even compare the imagePath variable to the real filepath. I want to do something like a VerifyEval of the variable and compare it to the path that I paste in for testing purposes. I tried "type"-ing the variable into an input element and then doing some sort of VerifyText against that but it didn't work. Am I overlooking a very easy solution?
Keep in mind I'm using Selenium IDE and I'd like to stick with this until I'm proficient at it before moving onto RC. Although if what I'm trying to do isn't possible in IDE, you can tell me that. Thanks in advance.
Edit: I'm not sure how clear I'm making this; for the time being I just want to compare ${imagePath} to the URL that I'll paste in myself. Once I'm done with that I can start figuring out how to define the accepted filepath/filename conventions.
If your ultimate intention is to verify that the stored variable match a specific format, then you can use verifyeval function eg.
verifyEval | storedVars['imagePath'].search("ur reg ex")>0 | true
or any of the javascript string methods to do the comparison
In LaTeX, how can I define a string variable whose content is used instead of the variable in the compiled PDF?
Let's say I'm writing a tech doc on a software and I want to define the package name in the preamble or somewhere so that if its name changes, I don't have to replace it in a lot of places but only in one place.
add the following to you preamble:
\newcommand{\newCommandName}{text to insert}
Then you can just use \newCommandName{} in the text
For more info on \newcommand, see e.g. wikibooks
Example:
\documentclass{article}
\newcommand\x{30}
\begin{document}
\x
\end{document}
Output:
30
Use \def command:
\def \variable {Something that's better to use as a variable}
Be aware that \def overrides preexisting macros without any warnings and therefore can cause various subtle errors. To overcome this either use namespaced variables like my_var or fall back to \newcommand, \renewcommand commands instead.
For variables describing distances, you would use \newlength (and manipulate the values with \setlength, \addlength, \settoheight, \settolength and \settodepth).
Similarly you have access to \newcounter for things like section and figure numbers which should increment throughout the document. I've used this one in the past to provide code samples that were numbered separatly of other figures...
Also of note is \makebox which allows you to store a bit of laid-out document for later re-use (and for use with \settolength...).
If you want to use \newcommand, you can also include \usepackage{xspace} and define command by \newcommand{\newCommandName}{text to insert\xspace}.
This can allow you to just use \newCommandName rather than \newCommandName{}.

I think you probably want to use a token list for this purpose:
to set up the token list
\newtoks\packagename
to assign the name:
\packagename={New Name for the package}
to put the name into your output:
\the\packagename.
