Coding the operand field

There must be at least one blank between a statement and its operands. See the specific statement for a list of the available operands for the statement. The following conventions are used in this manual to describe statement operands:

• Required operands are not enclosed in brackets and are listed first in alphabetical order. Optional operands follow the required operands. They are enclosed in brackets and are also listed in alphabetical order.
• An operand is described by its keyword name in uppercase, followed by an equal sign and a variable value that you can choose.
• You must code the following symbols exactly as they appear for the statement description:

  Asterisk	*
  Comma	,
  Dollar sign	$
  Equal sign	=
  Hyphen	-
  Parentheses	( )
  Period	.
  Plus sign	+
  Quote	'

• Lowercase italicized letters and words represent variables for which you can supply specific information. The operand description, which follows each statement description, lists the valid variable values and any restrictions for the values.
• The following symbols are used for the operand format and should never be coded as part of an operand value:

  Braces	{ }	A stack of items, each contained within braces, represents a set of alternatives, one of which must be chosen. For example: {YES} {NO}
  Vertical Bar	|	Items separated by vertical bars represents a set of alternatives, one of which must be chosen. For example: {YES|NO}
  Brackets	[ ]	Information contained within brackets represents an option that can be included or omitted when coding the operand. For example: [,DISPLAY=(a,b[,c,d])]
  Ellipsis	…	An ellipsis indicates that a number of items may be coded. For example: (integer,...)
  Underscore	_	An underscored item represents a default value that need not be coded. For example: [,RTR={YES|NO}]

  If a set of stacked items or items separated by vertical bars, each contained within braces, is included within a set of brackets, one of the items must be chosen if the bracketed operand is coded.
