Although discrete parameters values look like command keywords,
do not confuse the two. In particular, be sure to use colons and
spaces properly. Use a colon to separate command mnemonics from
each other. Use a space to separate parameters from command
mnemonics.

Boolean Parameters. Boolean parameters represent a single binary
condition that is either true or false. There are only four possible
values for a Boolean parameter.

Examples of Boolean parameters:

O N

Boolean TRUE, upper/lower case allowed

OFF

Boolean FALSE, upper/lower case allowed

1

Boolean TRUE

0

Boolean FALSE

Examples of Boolean parameters in commands:

100 OUTPUT
