DCheckField S 1A based(FieldToCheck) VARYING

My question is How do I define the varible CheckField so that when FieldToCheck points to a variable that is say 10A in length Checkfield will adjust accordingly. My understanding from the documentation is that by using BASED(pointer) it should adjust itself but that doesn't seem to be working that way

Don:

Keep in mind that if the field that is referenced by your pointer isn't also a VARYING field, then all bets are off.

Back in some calling proc, there is an actual definition of some memory. Think of that like an actual street address -- e.g., 1106 N. 3rd Av. The pointer indicates a physical street address, but it says nothing about the structure at that address.

Now, in your called proc, you provide a description of that street address -- e.g., the third house from the intersection on the east side of the street. Your definition in the called proc needs to have an indication of the structure that should exist at the address. Your called proc doesn't need actual source code to state the address explicitly since the pointer does that for you, but it does need source code that describes the memory /appropriately/. You wouldn't get far with a description that says "apartment 402 of the complex that is third from the intersection on the east side of the street".

You seem to be trying to reference fixed-length fields with varying-length definitions. The memory isn't structured the same for fixed- and varying-length fields.
