Re: RdLine with variable length field

Hi Larry,

I'm at V5R4, and have no way to detect the difference between VARYING(2) and VARYING(4) on my release, so I hard code it in a constant.

If you're on 6.1 and want to avoid hardcoding, you can calculate it as follows:

VARPREF = %addr(field:*data) - %addr(field)
