OPT

For terminal operator
.-OPT--=--BLKSUP-------. >>-+----------------------+------------------------------------>< \| .-BLKSUP---. \| '-OPT--=--+----------+-' '-NOBLKSUP-'
macroinstructions:	USSMSG
dependency:	BUFFER

For VTAM operator
.-OPT--=--NOBLKSUP-----. >>-+----------------------+------------------------------------>< \| .-NOBLKSUP-. \| '-OPT--=--+----------+-' '-BLKSUP---'
macroinstructions:	USSMSG
dependency:	none

Indicates if extraneous blanks are to be suppressed from the defined message.

OPT=BLKSUP: Specifies that extraneous blanks are to be suppressed from the message. Any sequence of two or more blanks is to be converted into a single blank.
OPT=NOBLKSUP: Specifies that extraneous blanks are not to be suppressed from the message. Any sequence of two or more blanks is to be presented unchanged in the message.

Note:

For terminal operators VTAM® ignores the OPT operand, if both OPT and BUFFER are specified.
It is recommended that OPT=NOBLKSUP be used for any message that is part of a tabular display.
If the OPT operand is omitted or is specified with a null value (OPT=), VTAM uses the OPT value specified for this message ID in the next USS table searched.
