RE: Variable length variables and data queues -- RPG400-L

Yeah - that is my understanding

if the grey matter serves me correctly, the max size of the dtaq is about 
16meg


the length specified on the CRTDTAQ is the equivalent of a record length.
if you create it with a length of 128, and write 10 bytes to it, it "takes" 
(or, "uses" )   128 bytes...

<at the risk of starting a bun fight,>
kind of takes you back to the days of the s36 flat files..
