String sets its Value to "False" - vb.net

Question

So, I'm currently working on a program that should create Lua-Scripts for the Unitale-Engine. I added a "New Project" button which should create a new project file when you click it. I want this file to contain the default project-file-text. So i did this:
Dim File1 As String = "monster{" & vbNewLine & "COMMENTS=Ribbit, ribbit.;Croak, croak.;Hop, hop.;Meow." & vbNewLine & "COMMANDS=Compliment;Threaten" & vbNewLine & "DEFAULT_SPRITE=None" & vbNewLine & "NAME=Froggit" & vbNewLine & "HP=10" & vbNewLine & "ATK=1" & vbNewLine = "DEF=0" & vbNewLine & "CHECK_MESSAGE=Life is difficult for this enemy." & vbNewLine & "HandleAttack=" & vbNewLine & "OnDeath=" & vbNewLine & "HandleCustomCommand=" & vbNewLine & "}"
Dim File2 As String = vbNewLine & "encounter{" & vbNewLine & "DEFAULT_MUSIC=Fight" & vbNewLine & "ENCOUNTER_TEXT=Froggit hops close." & vbNewLine & "NEXTWAVES=1" & vbNewLine & "WAVETIMER=6" & vbNewLine & "ARENASIZE=155;130" & vbNewLine & "ENEMIES=Froggit" & vbNewLine & "ENEMYPOSITIONS=0;0" & "EncounterStarting=" & vbNewLine & "EnemyDialogueStarting=" & vbNewLine & "EnemyDialogueEnding=" & vbNewLine & "DefenseEnding=" & vbNewLine & "HandleItem=" & vbNewLine & "HandleSpare=" & vbNewLine & "EnteringState=" & vbNewLine & "Update=" & vbNewLine & "}"
Dim File3 As String = vbNewLine & "waves{" & vbNewLine & "1=Do Nothing" & vbNewLine & "}" & vbNewLine & "end"
My.Computer.FileSystem.WriteAllText(My.Computer.FileSystem.SpecialDirectories.MyDocuments & "\UnitaleMaker\Projects\" & PJNBox.Text & ".umproj", File1 & File2 & File3, False)
Yes, that is a lot of text. The problem is, that File1 always sets its value to "False" when it is declared. I thought that is because the string is too long, so I split it to 3 parts, but it doesn't work.
Any help would be apprechiated!

Starting with VB 14 (Visual Studio 2015), you can span String literals across multiple lines. VB 14 also adds String interpolation, which makes for much cleaner code. You could write your code like the following which would have kept you from having made your mistake of & vbNewLine = "DEF=0" &and would overall make the code easier to read.
I am also assuming you forgot a newline in "ENEMYPOSITIONS=0;0" & "EncounterStarting=" and I have indented the parts between the {}. I combined File1, File2, and File3 back into a single string since you stated you broke them up in the question, I assumed you'd rather have it all in one string.
Dim File1 As String = "monster{
COMMENTS = Ribbit, ribbit.;Croak, croak.;Hop, hop.;Meow.
COMMANDS=Compliment;Threaten
DEFAULT_SPRITE=None
NAME=Froggit
HP=10
ATK=1
DEF=0
CHECK_MESSAGE=Life Is difficult For this enemy.
HandleAttack=
OnDeath=
HandleCustomCommand=
}
encounter{
DEFAULT_MUSIC = Fight
ENCOUNTER_TEXT =Froggit hops close.
NEXTWAVES=1
WAVETIMER=6
ARENASIZE=155;130
ENEMIES=Froggit
ENEMYPOSITIONS=0;0
EncounterStarting=
EnemyDialogueStarting=
EnemyDialogueEnding=
DefenseEnding=
HandleItem=
HandleSpare=
EnteringState=
Update=
}
waves{
1 =Do Nothing
}
End"
My.Computer.FileSystem.WriteAllText($"{My.Computer.FileSystem.SpecialDirectories.MyDocuments}\UnitaleMaker\Projects\{PJNBox.Text}.umproj", File1, False)

Please learn to use string.format.
Also I changed & to new line in file2:
"ENEMYPOSITIONS=0;0" & "EncounterStarting="
I just assumed you forgot to add new line there.
Alss Environment.NewLine is the best option for new lines as it is universal.
Dim File1 As String = String.Format("monster{{{0}COMMENTS=Ribbit, ribbit.;Croak, croak.;Hop, hop.;Meow.{0}COMMANDS=Compliment;Threaten{0}DEFAULT_SPRITE=None{0}NAME=Froggit{0}HP=10{0}ATK=1{0}DEF=0{0}CHECK_MESSAGE=Life is difficult for this enemy.{0}HandleAttack={0}OnDeath={0}HandleCustomCommand={0}}}", Environment.NewLine)
Dim File2 As String = String.Format("{0}encounter{{{0}DEFAULT_MUSIC=Fight{0}ENCOUNTER_TEXT=Froggit hops close.{0}NEXTWAVES=1{0}WAVETIMER=6{0}ARENASIZE=155;130{0}ENEMIES=Froggit{0}ENEMYPOSITIONS=0;0{0}EncounterStarting={0}EnemyDialogueStarting={0}EnemyDialogueEnding={0}DefenseEnding={0}HandleItem={0}HandleSpare={0}EnteringState={0}Update={0}}}", Environment.NewLine)
Dim File3 As String = String.Format("{0}waves{{{0}1=Do Nothing{0}}}{0}end", Environment.NewLine)
My.Computer.FileSystem.WriteAllText(My.Computer.FileSystem.SpecialDirectories.MyDocuments & "\UnitaleMaker\Projects\" & PJNBox.Text & ".umproj", File1 & File2 & File3, False)
