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.
