Re: justifying a character variable

["Joe Sarnowski" <jfs@xxxxxxx>]

Here's another way to right justify a character field.  In this example, I'm
moving a 7 character field (wkfld = '12345  ') to another 7 character field
(svfld = '  12345').

D wkfld                       s                        7        inz('12345
')
D svfld                         s                        7
D ctr                            s                        3   0

C                               eval                ctr = %scan(' ': wkfld)
C                               if                    ctr > 0 and ctr < 8
C                               eval                svfld = %replace(wkfld:
svfld:
C                                                        9 - (%scan(' ':
wkfld)))
C                               else
C                               eval                 svfld = wkfld
C                               endif

This code will check for at least 1 character in the 1st field, then moves
it to the 2nd field, else it just moves the entire 1st field to the 2nd.
