What is the purpose of the comma operator in GWBASIC?

Answer 1

The GWBASIC comma operator is used to format the output of the PRINT command, placing the value to be printed in the next print zone rather than immediately after the previous value. Note that GWBASIC divides each line into zones of 14 spaces each.

The comma operator also has other purposes, such as when filling a string with the same character. For example:

10 X$ = STRING$(10,45)

20 PRINT X$"HELLO WORLD"X$

RUN

----------HELLO WORLD----------

The comma operator is also used to separate the dimensions of a multi-dimensional array, such as the following 2x3 array:

A(2,3)
