<title>Define a SUbroutine within Embperl</title>
</head>
<body>
Here we define a subroutine<P>
NOTE: It must be defined within [[! ... !] to avoid redefinition!
[!
# Here we add a comment
sub Hello
{
# not much to do ...
return 'Hello world' ;
}
!]
Now we call the subroutine: [+ Hello () +] <P>
$XXXXXX::var = [+ defined ($XXXXXX::var)?$XXXXXX::var:'<undef>' +] <br>
Setup some variable outside our namespace, which should not be cleaned up<br>
[- $XXXXXX::var = 1 -]
$XXXXXX::var = [+ defined ($XXXXXX::var)?$XXXXXX::var:'<undef>' +] <br>
[! sub CLEANUP
{
print LOG "This will be called before variable cleanup\n" ;
undef $XXXXXX::var ;
}
!]
<P>Ok.<P>
</body>
