USING
instruction: format printed output
Print Using format$;variable list
USING is always employed with the PRINT command to allow subtle changes in the way output is printed from a list of variables. The format string contains special characters, and each one has a different effect, as explained below.
~
tilde character [Shift]+[#]
Every ~ in the string variable is replaced by a single character from left to right, taken from an output string. For example:
E> Print Using "This is a ~~~~~~ example";"simple"
#
hash character
Each # specifies one digit at a time, to be printed out from a given variable, with any unused digits being replaced by spaces. For example:
E> Print Using "###";123456
+
plus character
This adds a plus sign to a positive number or a minus sign if the number is negative. For example:
E> Print Using "+##";10 : Print Using "+##";-10
-
minus character
This gives a minus sign to negative numbers only. Positive numbers will be preceded by a space. For example:
E> Print Using "-##";10:Print Using "-##";-10
