Weirdness in screen program (not that long!)

[Peter Bateman]

Mark:

If you have support check with customer support. This sounds vaguely 
familiar.
Check for reserve words. Do not use a PowerHouse keyword as an identifier.

Bad syntax
TEMPORARY ITEM ...
ITEM is a reserved word
If you must you can say:-
TEMPORARY %ITEM ...


If you do NOT already have a CLUSTER statement before the TEMP field
put one in.
CLUSTER OCCURS WITH DETAIL
.
.
.
ALIGN(1,4,20)
CLUSTER
FIELD <temporary item>

As a last resort if QUICK wants to eat a field give it one to eat.
i.e.

TEMPORARY t_DUMMY CHAR * 2 INITIAL "  "

CLUSTER
FIELD T_DUMMY NOID NOLABEL
FIELD <temporary item>


Good luck,
Peter Bateman

>Disabling the last field in the cluster will resort in the prompt of the

>And again, entering a correct value will have the program run as intended.
