Omitted operands

When a keyword operand is omitted, the default value specified for the corresponding keyword parameter is the value assigned to the parameter. When a positional operand or sublist entry is omitted, the null character string is assigned to the parameter.

Notes:

Spaces appearing between commas (without surrounding apostrophes) do not signify an omitted positional operand or an omitted sublist entry; they indicate the end of the operand field.
Adjacent commas indicate omission of positional operands; no comma is needed to indicate omission of the last or only positional operand.

The following example shows a macro instruction preceded by its corresponding prototype statement. The macro instruction operands that correspond to the third and sixth operands of the prototype statement are omitted in this example.
