Robert
First of all I want to sincerely thank you for taking some time to reply to my question. I tried your suggestion but I got the error
(search:(\d+)=([/\w+]+,?) replace:_2 + textArea.getCaretLine() + _2 )

"Attempt to resolve method: getCaretLine() on undefined variable or class name: textArea : at Line: 3 : in file: inline evaluation of: ``__internal_replace(ns) { this.callstack.set(0,ns); return (_2 + textArea.getCare . . . '' : textArea .getCaretLine ( ) ".

Not to be deterred, I tried view.getEditPane().getTextArea().getCaretLine() instead of textArea.getCaretLine(). Still, no luck..

Btw, what I want to achieve is that I simply want a line ctr wedged between two regular expression in a beanshell script.

Please let me know if & what I am doing wrong..

Thanks once again
SK.

1. It have to work!
When I change "textArea" to i.e. "textArey" I get the same error message except that the undefined variable is called "textArey".
This means: You may have written "textArea" not correct (case sensitiv!) or this variable is really not defined. In last case there's going somthing wrong... I would try to reinstall jedit.

2. May be You cannot achieve Your goal with simple search & replace. Instead record a macro and try to complete it.
