How to get an INPUT ALFAVAR (AD=MYRT'_') right justified?

I would get my ALFAVAR(A2) right justified .

RESET CV-VAR
INPUT ALFAVAR (AD=MYRT’_’ CV=CV-VAR) → (ALFAVAR='1 ')
DISPLAY ALFAVAR (EM=H(2)) —> (F140) Left just
END

How can I get (40F1) right justified ?

As long as you do not modify the value on the screen the variable will not change.
Try to modify it to ’ 2’ and you will see it will print as 40F2.

When you enter just ‘2’ you will get F240 as well, because AD=R only affects the on-screen display value, nothing else.

If you require it right justified at any rate you will need to MOVE RIGHT after the INPUT.
