Re: Externally-Described Field used as array name.

Hi Patrick,

I'll try<G>:

The compiler sees PDLB02 in the data structure first, and allocates memory
for it there.

Then it sees PDLB02 in the input specs and wants to allocate memory for it
within the input buffer, but it can't have a unique field name pointing to
two different memory locations.

I believe with V5R1 you are able to use the data structure name (which your
example doesn't have) as a qualifier to the field name, so you could indeed
have the duplicate name.  But you'd have to be aware that the value in one
would not automatically be copied to the other.
