numbered registers and regexp's

Hey gang,

In Perl matching segments can be captured from a regular expression into special numbered registers:

$refdes = "CA543A" ;
$1 =~ /$[A-Z]+$[0-9]+..*/ ; $1 winds up containing "CA"

The SKILL manual says you can do the same but gives no examples of how to reference the numbered registers. Anyone try this before and/or have some examples?

TIA,

Hi Chris,

A snippet...

rexCompile("\$[a-zA-Z]+\$\$[0-9]+\$")
foreach(pin, pins
pinNumber = pin ->number
if(rexExecute(pinNumber) then
loc = pin ->xy, x = car(loc), y = cadr(loc)
vPin = list(y, rexSubstitute("\\1")), hPin = list(x, rexSubstitute("\\2"))

Cheers, Dave
