i've got the following code fragment:

Code:

01 WS-NUMFMT    PIC Z(12)9.99- BLANK WHEN ZERO.
01 MNTH_ONG_LIAB_AMT    PIC X(11) JUSTIFIED.
...
 
MOVE 12345.67 TO WS-NUMFMT
MOVE WS-NUMFMT TO MNTH_ONG_LIAB_AMT


this produces the correct result : "12345.67-"

however, with the definition :

01 WS-NUMFMT PIC -Z(12)9.99 BLANK WHEN ZERO.

... I lose the sign, and get only "12345.67"

any help appreciated !

How can moving a positive value to WS-NUMFMT produce a "correct" (as you say) negative result?

I would expect the "-" in the edit mask to be replaced with a blank since your value is positive.

You need to show results as produced, not just say what they are.

I think at a minimum you have a typo; at the maximum you are lying. Code:
Code:
000800  WORKING-STORAGE SECTION.                                       
000900  01  WS-VARS.                                                   
001000      05  WS-NUMVAR1              PIC Z(12)9.99- BLANK WHEN ZERO.
001100      05  WS-NUMVAR2              PIC -Z(12)9.99 BLANK WHEN ZERO.
001200  PROCEDURE DIVISION.                                             
001300      MOVE 12345.67               TO  WS-NUMVAR1                 
001400                                      WS-NUMVAR2.                 
001500      DISPLAY 'NUMVAR1 >' WS-NUMVAR1 '<'.                         
001600      DISPLAY 'NUMVAR2 >' WS-NUMVAR2 '<'.                         
001700      DISPLAY ' ' .                                               
001800      MOVE -12345.67              TO  WS-NUMVAR1                 
001900                                      WS-NUMVAR2.                 
002000      DISPLAY 'NUMVAR1 >' WS-NUMVAR1 '<'.                         
002100      DISPLAY 'NUMVAR2 >' WS-NUMVAR2 '<'.                         
produces results of
Code:
NUMVAR1 >        12345.67 < 
NUMVAR2 >         12345.67< 
                             
NUMVAR1 >        12345.67-< 
NUMVAR2 >-        12345.67< 
These results are precisely as expected -- and completely contradict what you posted. Hence my earlier statement that you have typo(s) or are lying.

there was an obvious typo in the original post; but equally true you didn't read the post.

error on my part was not using a floating sign. The definition should have been:

01 WS-NUMFMT PIC -(12)9.99 BLANK WHEN ZERO.


The 'lying' suggestion both unprofessional and unbecoming of a 'moderator'

I recommend you either to RTFM, or move your questions to the Beginners Forum.
No way to discuss in your manner here.

I stand by my reply.

You still moved an unsigned number to WS-NUMFMT, and you have not replied to that.

Your post: MOVE 12345.67 TO WS-NUMFMT

You CANNOT, under any circumstances, get the value 12345.67- when you move 12345.67 to your WS-NUMFMT variable. I showed this in my code post. So when you tell us you got certain results, and it has been proved beyond any doubt that you CANNOT get those results with what you posted, what conclusion should we draw? Furthermore, I did NOT accuse you of lying -- what I said was that you either have a typo or you were lying.

Start posting on Beginners and Students Forum as it is much more suited for your skill set. It doesn't matter how many "years" of experience you claim, you are a beginner.
