Primary Commands

These are stand-alone commands which provide the primary functionality in a script. These
commands may rely on one or more of the Secondary Commands to provide values for some
parameters. The preprocessor will require that these commands appear only as the first element
of a command line. The start of a command line is delimited by any of the following:
The start of a new line of text in the script

A semicolon (;)

A left brace ({)

set
The set command assigns a value to a variable. Syntax:
set <variable> <value>
where <variable> is a word, and <value> can be defined in one of the following ways:
A quoted string

A word

A variable reference

A value generated via one of the string secondary commands (compare, match, first, etc.)

A value generated via the expr secondary command

A value generated via the format secondary command

A value generated via the expr timestamp command

unset
This command removes the definition of a variable within a script. Syntax:
unset <variable>
where <variable> is a word.
scan
The scan command is analogous to the C language scanf(). Syntax:
scan <variable> <format string> <value 1> <value 2>... <value n>
where <variable> a variable reference, and <format string> is a quoted string. Each of the <value
x> elements will be a word.
sleep
The sleep command suspends execution of the script (puts it to 'sleep') for the specified number of
seconds. Syntax:
sleep <value>
where <value> can be a word, a quoted string or a variable reference.
