Appendix
Blank Delimiters
Blank delimiters are the easiest to use. A blank delimiter is one or more spaces, tabs, or new lines (a carriage-return/line-feed pair) in any order. To define a macro using the blank delimiter, input more spaces, tabs, or new lines surrounding the parameter list.
When the macro defined with the blank delimiter is called, each delimiter will match a series of spaces, tabs, or new lines. Each parameter in the call begins with the first non-blank character, and ends when a blank character is found.
This example shows blank delimiters' use in source text:
%*DEFINE (X1 X2 X3) (P2=%X2, P3=%X3) %X1 assembler A51
This example shows blank delimiters' use in output text:
P2=assembler, P3=A51
