About this task
A comma is the continuation character. It indicates that the instruction
continues to the next line. The comma, when used in this manner, also
adds a space when the lines are concatenated. Here is how the comma
continuation character works when a literal string is being continued
on the next line.
SAY 'This is an extended',
'REXX literal string.'
The comma at the end of the first
line adds a space (between
extended and
REXX when
the two lines are concatenated for output. A single line results:
This is an extended REXX literal string.
The following two instructions are identical and yield the same
result:
SAY 'This is',
'a string.'
SAY 'This is' 'a string.'
The space
between the two separate strings is preserved:
This is a string.
