Updating a program described file

["Tim Gornall" <tgornall@xxxxxxxxxx>]

I have an FTP script source member that I need to update dynamically.
Basically I am attempting to update a source physical file member from
within RPGLE.  I can read the file (qclsrc) member without issue, but can't
get it to compile with update logic.  I've tried a bunch of different
things, too much to put in this text.  Here is an example of my code.  Does
anyone have an example?  Thanks, Tim
