Thanks to Violaine, Enhancement request

Hi Violaine,

Thanks for your presentation at the TEC conference on Tuesday, and your 
help afterward.  It was a useful presentation and it was also nice to put 
a face to the name.

Here is my request, posted to the list as requested.
I really like regular expression (RE) search.  What I would like is 
support for RE capture groups for search/replace.  I am pretty sure this 
is possible in the Eclipse Java editor if that helps any... I don't know 
if LPEX can call that code or not.

For example, suppose I have a display file with screen fields which are 
prefixed by a letter 'sf' (screen field) to denote make them easy to 
identify in my program.  I want to do crazy display things with them (like 
randomly change colours), so I have an DSPATR(field) for each of them, 
prefixed with an 'sa' (screen attribute) and name the same as the field. 
So now I have the following field names a bunch of places in my program

sName
sAddr1
sAddr2

aName
aAddr1
aAddr2

Now, for some reason I want to change Addr1 and Addr2 to be Adrss1 and 
Adrss2.  This is bit silly, I know, but bear with me - I have had valid 
reasons to do this, but of course now I can't remember any. :)

What I would like to do is:

Find:  \((s|a)\)Addr\((1|2)\)
Replace: &1Adrss&2

So \( and \) delineate a 'capture group', with &1 and &2 being 
substitution variables corresponding to the capture groups as they occur 
from left to right in the expression.  I would end up with:

sName
sAdrss1
sAdrss2

aName
aAdrss1
aAdrss2

everywhere in the program with one fell swoop.

In the case of nested groups:

\(\((1|2)\)(ack|syn)\)someMoreStuff

&1 would contain one of '1ack', '2ack', '1syn', '2syn' and &2 would 
contain '1' or '2'.

I imagine this would be difficult to implement, but it can produce some 
really nice results once you get the hang of it.

Thanks for all your work tracking these requests,
Adam
