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.
