does "infile1.txt" exist? is it being read correctly? with your code, if there is a problem with the file there is no message telling you this, it just skips the input code.

Try adding this to your infile process:

assert (not ENDFILE(inFile) ) report "Reached end of file or there was an error" severity failure.

also, with your code, a meta value on the input_tmp would return a 0 to rxn_re.

Btw, its a bad habit to leave large bits of code commented out.

And Please use the code tags around your code next time.
