6.3.1 Directives That Define Substitution Symbols

You can manipulate substitution symbols with the .asg and .eval directives.

• The .asg directive assigns a character string to a substitution symbol.

For the .asg directive, the quotation marks are optional. If there are no quotation marks, the assembler reads characters up to the first comma and removes leading and trailing blanks. In either case, a character string is read and assigned to the substitution symbol. The syntax of the .asg directive is:

.asg["]character string["], substitution symbol

Example 3 shows character strings being assigned to substitution symbols.
