Message appears to be saying that lmitds is already defined elsewhere.

This is puzzling, to me.

When I use an F-spec for the file named lmit, I can

auto-load an array thus -

flmit if e k disk
...
d myds ds
d custarrdata
d lcust1 overlay(custarrdata)
d lcust2

overlay(custarrdata:*next)

d lcust3

overlay(custarrdata:*next)

d lcust4

overlay(custarrdata:*next)

d lcust5

overlay(custarrdata:*next)

d lcust6

overlay(custarrdata:*next)

d lcust7

overlay(custarrdata:*next)

d lcust8

overlay(custarrdata:*next)

d lcust9

overlay(custarrdata:*next)

d lcus10

overlay(custarrdata:*next)

d custarr overlay(custarrdata)
d dim(10) like(lcust1)

but when I remove the F-specand c/ to an external desc data

struc it doesn't work

d lmitds e ds extname(lmit)

*RNF3315 20 10 The Name entry is already defined on a

Definition

Specification; defaults to blanks.

*RNF7030 30 1 The name or indicator is not defined.

*RNF7301 30 1 Position of subfield is greater than

length of data

structure; specification ignored.


Nothing else changed, only changed from an F-spec to ext

desc data struc ? ?

Anyone have any explanation for this or run across this before?
