In DDS for display, we can right-justify a character field by using the
CHECK(RB) keyword
ie. a input of  'ABCD   '  would give us '   ABCD'.

Q. Is there a CHECK(LB) for left-justify? 
if not, I would appreciate any suggestions on how to get the effect as
simple as possible, please.. 
KK Liu.

ps. sample code...

Then, CALL TSTDSPC and enter '   ABC  ' at the screen.
Program bombs with CPF error because of the spaces in front....
Monitoring for error is not the solution!
