if my variable contains
$myvar="this=is=a=test=string";

and i do
($x,$y)=split("=",$myvar);

then $x becomes "this"
and $y becomes "is"

but how do i split it so that
$x becomes "this"
and $y becomes "is=a=test=string";

ie $y becomes the rest of the string

thanks

try this...

this script in flexible in that tomorrow if you have one more = field in myvar it would still work.

Eg. try this script with $myvar="this=is=a=test=string=for=testing";
==================================================
#!/usr/local/bin/perl

$myvar="this=is=a=test=string";

$x=substr($myvar,0,index($myvar,"="));
$y=substr($myvar,(index($myvar,"=")+1),length($myvar));

print $x,"\n",$y,"\n";

There is a thirt parameter for split available.
Try
($x,$y)=split("=",$myvar,2);

Or this:

($x,@y)=split("=",$myvar);
$y=join("=",@y);
