Re: Varying Length fields, and LikeRec

[Tony Carolla <carolla@xxxxxxxxx>]

Thanks!  That clears it up.  I guess I assumed that DSPPFM would show
the actual offsets within the record, based on the length of the
varying fields.  I am getting x'0034', or 52, which is the correct
length.

I am glad the VARLEN and VARYING keywords work like that.
