Re: a strange RPG program

["Buzz Fenner" <nick_exxon@xxxxxxxxxxx>]

What it sounds like you have is a situation where a source member is 
actually opened for input/update in an RPG program.  I do this often 
with DDS source members; reading the lines of source code (92 character 
record spec) and modifying the lines I need (usually the select/omit 
criteria).  A CL "wrapper" is required to issue an OVRDBF command to DDS 
member; then execute the RPG program to read the source code and make 
the modifications.
