Hi,

I Have a variable of X(40) . When a pass a value to this variable it is not necessary that i have to pass a variable of length 40. So there will be trailing spaces. How do i remove these space?

May be not need move a value 0f 40 length.Check your data attribuate.

or cut the value to your need.

xx pic x(40)
yy pic x(10)
yy = xx(1:10)

A COBOL variable is fixed length. If the value is HI it is followed by 38 spaces; if it is HI HOW ARE YOU then it is followed by 26 spaces. If you want to know where the last non-space character is, start at the end of the variable and look for a non-space character one by one. You can replace the trailing spaces by some other character, but you're always, always, always going to have 40 characters in the variable. COBOL is not like C where variables can have different lengths.

Hi,
The method Robert has suggested will work fine to find out actual length of data in a variable. Here is the logic

Perform varying I from 40 by -1 until I = 0 or var1 (I: 1) not equal spaces
End-perform

If var1 is having value "HI" I will returns 2
If var1 is having value "HI how are you" I will returns 14

here you get actual length of data in variable var1

Thanks,

How does that remove the "unwanted" spaces?
