Debugging *is* an issue, but its a small one. I find it helpful to first focus on the parsing itself (i.e. just get the *grammar* right) and then go back and retrofit the actual application. As far as debugging, you can still debug this using the perl debugger just like you debug anything else. The only difference is that it is a bit more challenging to insert a breakpoint. To insert a breakpoint in some bit of buried subroutine, simply insert the following statement: $DB::single=1; and voila, you will break there with all of the access you normally have in the debugger. IMHO, if you are looking for ease of debug, you need to avoid PR::D altogether... ;-) -- Intel, Corp. 5000 W. Chandler Blvd. Chandler, AZ 85226 -- Intel, Corp. 5000 W.
