Hi Guys,
I have the following requirement:
I have a variable TEMP which can receive positive or negative value. Irrespective of the value it receives I have to make it positive.
Can any one tell me if we have a function in COBOL to do this?
I require a function only to do this.. |

the COBOL manual will tell if the ABS function is available...
otherwise a good old ...
| Code: |
| if a <= 0 then a = -a |
( translated to a valid COBOL format ) will be enough |

| We can also achieve this by defining 'TEMP' as unsigned so that sign nibble from sending field will be dropped. |

| I would suggest that if you use the unsigned way, you comment this var and/or the code using it so it is clear that the intent is to calc abs value. |
