HI,
i have a record with several amount fields.
I want to check if any of these fields contain any alphabet.
I want to write it to an exception file in that case.
I am using inspect but dont want to inspect the code 26 times with each alphabet. |

IF AMT1 NOT NUMERIC
it's an error

Your requirement is not at all clear. If these fields are USAGE DISPLAY, and AMT1 has the value +10.75, it will be stored as 00000000000107E -- so how do you distinguish the legitimate, valid sign overlays from invalid alphabetic characters? If the fields are not USAGE DISPLAY, the problem is worse since both COMP-3 and COMP variables can have valid data fields that appear to be alphabetic characters (for example, -97994 stored as a PIC S9(05) COMP-3 value is 'pr(').
There is a link to the manuals at the top of this page. Click on it, find the COBOL Language Reference and Programming Guide manuals and read up in them on how COBOL stores data internally. Once you have done this, and can reformulate your question in a way that actually makes sense, we should be able to help you. |

Yesh i guess the requirement was not put corretly.
AMT1 is PIC X(10).
I Use the AMT = FUNCTION NUMVAL(AMT1) to extract the numeric value.
But if AMT1 contains any alphabet/non numeric chars the job abends, so i want to have a check before going to the intrinsic function and write those records(containing alphabets or special chars) to an exception file instead of performing the NUMVAL.
Sincere apologies .... |

A PIC X(10) and PIC S9(13)V99 have a different number of digits -- so you're still not explaining yourself very well.
Why not just say
| Code: |
IF AMT1 NUMERIC
COMPUTE AMT = FUNCTION NUMVAL(AMT1) |

@ Robert,
If AMT is say '9999fff763'
Will the above still work? |

Is it so hard for you to test? Code:
| Code: |
01 WS-VARIABLES.
10 AMT1 PIC X(10) VALUE '9999FFF763'.
10 AMT2 PIC S9(13)V99.
LINKAGE SECTION.
/
PROCEDURE DIVISION.
S1000-MAIN SECTION.
IF AMT1 NUMERIC
COMPUTE AMT2 = FUNCTION NUMVAL (AMT1)
DISPLAY 'AMT2 OK -- ' AMT2
ELSE
DISPLAY 'AMT1 FAILED NUMERIC TEST'
END-IF.
MOVE '1234567890' TO AMT1.
IF AMT1 NUMERIC
COMPUTE AMT2 = FUNCTION NUMVAL (AMT1)
DISPLAY 'AMT2 OK -- ' AMT2
ELSE
DISPLAY 'AMT1 FAILED NUMERIC TEST'
END-IF.
GOBACK. |
produces output of
| Code: |
AMT1 FAILED NUMERIC TEST
AMT2 OK -- 00012345678900{ |
