Hot Keyboard provides different function types.

Special functions

GoTo <label>
	Works within "Evaluate Expression" macro only. Transfers the execution
	line to the one labeled with <label>. Does nothing in other cases.

SetVar (<$variable>, <value> [, <scope>])
	Sets value of the <$variable> variable to <value>. If <scope> is present
	and is non-zero, the variable value is saved on Hot Keyboard exit and
	loaded back on the next run.


iif ((<condition>), (<true-expr>), (<false-expr>))
	Evaluates <condition> and if the result is non-zero evaluates the
	<true-expr>	sub-expression or evaluates the <false-expr> otherwise.
	The unused sub-expression is not evaluated at all.

Example:

label:
SetVar($msg, InputBox("Enter Email"))
iif ( (StrFind ($msg, "@") < 0), ( GoTo "label" ), (1) )
MessageBox($msg)
