reference. The <int *> elements will be either words or variable references.
expr
This command evaluates an arithmetic expression and returns the result. The expr command will
only be used in combination with the set command to generate a value for a variable. Syntax:
expr <value> <operation> <value>
Each <value> will be either a word or a variable reference, and <operation> an arithmetic
operation.
timestamp
This command returns the current time of day as determined by the SLC. The timestamp
command will only be used in combination with the set command to produce the value for a
variable. Syntax:
timestamp <format>
where <format> is a quoted string.
format
The format command is analogous to the C language sprintf(). The format command will only be
used in combination with the set command to produce the value for a variable. Syntax:
format <format string> <value 1> <value 2>... <value n>
where <format string> will be a quoted string. Each of the <value x> elements will be a word, a
