Hi,
I’m not a expert but I think you do that if you go to:
Data ---> create format
Just follow the instructions
Format Names
Character format names must be 31 characters or
fewer in length, while numeric format names must
be 32 characters or fewer. For both format types,
names must contain only letters, numerals, or
underscores, and cannot start or end with a
numeral.
You can save a format
permanently by choosing a library other than
WORK.
I hope this help you.
