Specifying Input Padding
and Justification
You can specify padding and justification options in input fields by using the PAD and
JUST options of the #FLD statement.
If an input field is initialized with data during the display of a panel, data is always
aligned as described earlier in this section with a single exception. The exception is
that JUST=CENTRE is treated as JUST=LEFT. When Panel Services processes input
from the screen, input fields defined using the PAD and JUST operands are processed
using the following rules:
1. Trailing blanks and pad characters are stripped off unless the pad character is a
digit.
2. If JUST=RIGHT is specified for the field, leading blanks and pad characters are
stripped off, including the case in which the pad character is a digit.
3. If JUST=ASIS is specified for the field, trailing blanks and pad characters are
stripped off, but leading blanks and pad characters remain intact.
