Problem with parameter via CMD in CLLE

Hi

I have problem in processing the command which has these parameters defined as below, getting garbage value in first 4 position of parameter 2 LIBS1 which was earlier 2 when the LIBS2 parameter was not defined in my validity checking program.

After defining the LIBS2 parameter I am getting the garbage in first 4 while I was expecting it to be first two bytes? Any one seen this odd behavior?

COMMND XYZ

PARM.....
PARM KWD(LIBS1) TYPE(*CHAR) LEN(10) +
MAX(99) +
CHOICE('Library name') +
PROMPT('library 1')
+
PARM KWD(LIBS2) TYPE(*CHAR) LEN(10) RSTD(*NO) +
MAX(99) +
CHOICE('LIBRARY NAME') +
PROMPT('library 2')




Thanks,
