Unmatch variable

Hi All,

I don't now how AS/400 work, anybody can share with me ?

I have a program let say program A and this program will call sub program B,

01 LK-OPT PIC X VALUE '1'.
01 LK-NBR PIC S9(11)V9(4) VALUE ZERO.
....

CALL PGM "B" USING LK-OPT LK-NBR.


But in program B

LINKAGE SECTION.
01 WK-OPT PIC X VALUE '1'.
01 WK-NBR PIC S9(9)V9(4) VALUE ZERO.
..
..
MOVE 1 TO WK-NBR.



My question is why LK-NBR become 100 ? Shoud be 1. Is this error due to
different variable definition in A and B ?
