regexp for TCL 8.0

[Phil Biehl]

I'm having to convert some TCL 8.4 code down to the 8.0 version and am
having difficulty with an RE that works fine in 8.4 but fails in 8.0. I'm a
little embarassed because this seems simple but I can't seem to find an
answer that works.

I have a string that is in the form of: aaaa,1234,5678

I want to pick out the middle integer, 1234.

My code of the 8.4 persuasion looks like this: regexp {,(\d+),} $a b c
where $a is aaaa,1234,5678.

I'm assuming that \d is not supported in 8.0 as a decimal digit. What will
make this work in 8.0?

Also, is there a RE reference I can get that will explain the syntax ass it
pertains to 8.0? I know about the manpage at:
http://www.tcl.tk/man/tcl8.0/TclCmd/regexp.htm

Thanks!
Phil
