exit - exit program

SYNOPSIS

<exit [$code]>

DESCRIPTION
The exit function causes the script to terminate immediately. It can be used to quit a script from within a complicated set of function calls, which might otherwise require numerous returns and checks. An optional exit code $code may be given; the default is 0.

DIAGNOSTICS
exit returns nothing.

EXAMPLE

<A NAME=checklogin>
  <$pw = "FRvEhbGTRAWug">
  <pwencrypt $pass $pw>
  <IF $ret neq $pw>
    Your password is incorrect.
    <exit>
  </IF>
</A>

This function could be called to check a user's password at any point, without having an IF statement after every call: it only returns if the password is correct.

State information may be lost if $url hasn't been printed yet.
