General syntax rules

The general rules for coding the operands are the same as those for the operands in SUM/PURGE.

• If operands are to be continued, end the first line with a comma-blank.
• Comments are allowed after a blank.
• Comment lines are designated by an asterisk in column 1.
• If a value contains special characters such as blank, equal sign, or comma, enclose the value in quotation marks.
• Multiple values for a keyword are enclosed in parentheses and separated by commas.
• Multiple keywords may be coded on a single line, separated by commas.
• Undefined keywords, invalid values, missing delimiters, and such generate error messages.
