If a function is used without an header, you should put the function below in your script before calling it.

Thanks Afrow UK (Based on his idea of Function "JoinFiles")
 
 
Join two files in one (File1 + File2 = File3).
 
 
Syntax:
${FileJoin} "[File1]" "[File2]" "[File3]"
 
"[File1]"     ; Input File1
"[File2]"     ; Input File2
"[File3]"     ; Output File3
              ;  If [File3]="" Then add [File2] to [File1]
 
Note:
-Error flag if input files aren't exists
-Error flag if output file path isn't exists
 
 
 
Example1 (Join:  a.log + b.log = Z.log):
Section
	${FileJoin} "C:\a.log" "C:\logs\b.log" "C:\Z.log"
SectionEnd
 
 
Example2 (Add:  a.log + b.log = a.log):
Section
	${FileJoin} "C:\a.log" "C:\logs\b.log" "C:\a.log"
SectionEnd*/
