Problem:
A COBOL app in Net Express 4.0 outputs to a file.
How do you write to the file using different Font sizes?
Resolution:
There is no way to select/change the font (size) of the text being output to the file. You are simply outputting text.
There are PC_PRINTER_ routines in Net Express that allow you to specify the font and size to be used by the printer to print the file. Please refer to the online documentation for these library routines.
