Hi b.reddikumar:

Within debug key f1 (help)......
Goto the bottom place your cursor on rpg language examples and press enter.
Scroll to watch a variable press enter.

Watch a variable

RPG declaration: D FLD S 3A INZ('abc')

Debug command: WATCH FLD

Result: The program stops if the storage where the
variable FLD is located is changed to a new
value. The length watched is the size of
variable FLD, three bytes.


Debug command: WATCH FLD : 8

Result: The program stops if the storage starting
at where variable FLD is located is changed
to a new value. The length watched is the
size specified, eight bytes.


Comment: A maximum of 128 bytes may be watched with
one watch.

The storage location and not the variable is
watched. If the variable is in temporary
storage and the storage is used again, a
watch breakpoint may occur that is unrelated
to the original variable changing.

instead of keying "watch fld"
you can key "w fld"
or you can place your cursor on the field you want to watch and press f17

Hi b.reddikumar:

1. Set a breakpoint in your program
2. Execute your program ......

When it stops at your breakpoint you should be able to watch/F17
on any field that is used within your program.

< e d i t >(if the field you are trying to watch is in a sub-procedure try setting the breakpoint within that sub-procedure before watch/F17)< / e d i t >
