Re: Parameter passing with COBOL and REXX

Hello Matt,

The QREXQ API (like many APIs) is expecting 2 and 4 BYTE integers.  You have 
specified 2 and 4 DIGIT integers 
-- both of which result in 2-byte values.  2-byte integers will result when the 
number of digits in the PIC is 
5 or less, 4-byte integers will result when the PIC clause has more than 5 
digits.

Simply increase the number of digits and you should be fine.

Regards,
Simon Coulter.
