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
110 OUTPUT
