Re: Packed Numbers

Hi Rich,

It really depends on context. The CALL command, for example, always formats a number as 15,5. That's not a limit, really -- it's the only choice.

The CL programming language cannot declare a packed variable larger than 15 digits. (No clue why.) The same is true for CMDs... 15 digit max.

The limit in SQL, DDS and RPG has historically been 30 digits. In V5R2, they upgraded it to 31 digits (which puzzled me) and in V5R3, they increased it to 63 digits.

So it really depends on context as to whether the limit is 15, 30, 31 or 63 digits.

I'm trying to recall IBM's specifications on size contraints, if any, for packed data fields. For some reason, I thought packed data was limited to 15 digits, but I can't be sure about this and I'm seeing some data fields that seem to support larger field sizes.
