I need to be able to change the value of a parameter inside a LaTeX document without having to change it manually. I'll explain:
There is one main program that executes another smaller one. This smaller program computes some things and creates a .txt-file with a specific name and all its results inside. Then the main program executes the LaTeX file I have to create which will process the created .txt-file into a nice pdf (using commands such as
\openin\txtfile=\filename.txt and the package
Problem is that LaTeX needs to know the name of the newly created .txt-file. The main program knows the name it and will call the LaTeX file by using the cmd command
> latex texfile.tex. But this won't change the value of
\filename in any way.
Is there actually any possible way to change a value (of
\filename) inside the LaTeX file using the cmd? Because I have absolutely no clue and Google doesn't help me either...
