Parameters in Commands
There are four basic types of parameters: booleans, keywords, variables
and arbitrary block program data.
OFF|ON|0|1
(Boolean) This is a two state boolean-type parameter. The
numeric value 0 is equivalent to OFF. Any numeric
value other than 0 is equivalent to ON. The numeric
values of 0 or 1 are commonly used in the command
instead of OFF or ON. Queries of the parameter always
return a numeric value of 0 or 1.
