This sounds like an overlay problem. How is the DATA field defined?

Subject: Weird LDA stuff...
I have a program that's doing some funky stuff... It's not a new
program,
but it needed a recompile and ever since is behaving very badly.
I've had
it in debug, and this is what I've tracked it to... A 14 byte
character
array w/ 998 elements is getting loaded with at least the first 146
bytes of
the job's LDA when the program reads a record from a dataqueue.
The
dataqueue has nothing to do with the character array. When a value
is put
in the array, it is then overlaid by the value of the *LDA the next
time the
receive dtaq command is executed... Nothing is overlapping in the D
Specs... No sub-fields w/ the same name... Any thoughts?
This is the code that's executed where things go astray...
C* Read Record from Data Queue
C MOVE *ZEROS WAIT 5 0
C CALL 'QRCVDTAQ'
C PARM QNAME
C PARM QLIB
C PARM QLEN
C PARM DATA
C PARM WAIT
This is the D spec of the array "E"...
D E S 14 DIM(998)
This is the array prior to the receive dtaq cmd...
E CHAR(14) DIM(998)
(1-998) ' '
VALUE IN HEX
'4040404040404040404040404040'X
This is the array after the rcvdtaq cmd...
