i will check it out Francis,
thanks for the tip
i am getting a strange error in compiling a RPGLE ussing a PF
it is
1)Record-format name in externally-described file already
defined; record format ignored.
2)The name or indicator is not defined.
3)Expression contains an operand that is not defined.
All Record Formats for externally-described file ignored or
It compiles if i dont use this file
Agian i checked i am not ussing that record format, i am sure
can u throe some light into it?
