That's not actually the case. Varying length data is stored in an auxiliary data space, not the main data space. For allocated = 0, all of the data goes to the aux space. There is a locating value stored in the main space, which also has a pointer to the aux space. It's been 10 years since I looked at this in SST, so the details may be sketchy. If allocated > 0, then values that have a length within that value are stored in the main space, those longer are stored in toto in the aux space.

There were a couple interesting things as to recovering that aux space usage - the only time that happens is when I did a RGZPFM - updates don't recover, they just get the pointers changed to where the data is now. That's for performance, I always assumed.

I would like to describe a variable length field with a minimum of zero
length.

Is this possible?

Why must I have min length 1??

TEXTDATA 1000 COLHDG('MEMO TEXT')
VARLEN(1)
