Re: Entry Parameters

Hello Jim,

Despite Buck's very well explained append, because you are expecting Zoned 
Decimal values you 
can simply invoke the program with:

 CALL PGM(JIMCONEX/CHGAPOPEN) PARM('51' '990110' '51' '000120')

Note the 'quotation' marks -- yeah, I know they're apostrophes.
Note that no 'conversions' are neccessary.  The character values 'magically' 
become numbers.

Why does this work?

Regards,
Simon Coulter.
