Commodore Plus 4 - Conditional statements

PUDEF Abbr. pU
PUDEF "one to four characters"
Lets you replace with any other symbol the symbols displayed by subsequent
PRINT USING commands. You can replace blanks, commas, decimal points,
and dollar signs from PRINT USING commands that follow the PUDEF
command. You can issue as many PUDEF commands as necessary to print
formatted data according to your special purposes.
Characters are replaced by their position in the PUDEF command. The
default values for each position are used if you do not specify a different character
in the appropriate position.

When you want to replace all the blank spaces in the output printed by a
PRINT USING command, put the replacement character in the first position in
the PUDEF command. When you want to replace commas, put the replacement
character in the second position, and so on.
Because the computer recognizes replacement characters by position, you
must type the default values in their positions if the following two conditions are
true:
• You are not changing the default values.
• They appear in the PUDEF format before the characters you are changing.
If the default values appear after the changes, you can omit the defaults and
just end the command. For example, if you want to leave blanks and commas
when you change decimal points, you must place a blank and a comma in their
positions in the PUDEF command and then type the decimal point replacement
in the third position.
Examples: 90 PUDEF "//" Replaces blanks with slashes and decimal points with
apostrophes. Commas and dollar signs are
retained.
75 PUDEF " .bA" Replaces commas with decimal points, decimal
points with lowercase b's, and dollar signs with A's.
Blanks are retained.
