Thanks here is a  sample Session file from a commercial finite element
pre-post processor PATRAN, the file longer but the ideas are the same
so that let me give an example, say I would like to make write line 10
composed of some command line arguments: path+database_name, Also
there are some lines similar to this in the below sections of the
file. I am doing it with a if-elif-else clause checking the line
numbers with which I thought of there should be a better way and ended
up asking...
