RE: calling C from OPM RPG

Jared,

Just an FYI, but in regards to ILE RPG --> ILE C.  An ILE RPG program can
call and directly make use of any (most?)  functions in the ILE C/C++
runtime library....

atoi(), bsearch(), fopen(), printf(), ....


all you have to do is prototype the call and specify the use of the QC2LE
binding directory.


HTH,
Charles
