Assignment Statements
$ vbl = boolean_expression
Examples:
$ MANIA = (“TRUE” .EQS. “FALSE”)
$ TRUE = (1 .EQ. 1)
$ FALSE = (1 .EQ. 0)
$ YES = 1
$ NO = 0
Notes:
Here we have examples of assignment of a “truth value” or a boolean value.
The last two examples are ordinary numeric literal assignments. They illustrate the defaults for “true” (“yes”) and “false” (“no”).
