That's not exactly what I meant. I remember back in Delphi 7 (maybe
even as far back as D5), that I changed the execution point, so it can
re-execute a procedure but with different values - no need to
recompile or restart the application.

Delphi 2010 has improved on that by simply dragging and dropping the
execution point while in debug mode. I did some googleing and remember
I fiddled with the CPU registers to accomplish what I did, but
couldn't remember what registers.

Google found my exact answer. I see I can modify the CPU registers in
MSEide, but I don't think this is possible with Lazarus IDE. Just
tried, and it seems to work in MSEide - I'll do more testing to
confirm. The register in question was EIP.

Here is the google link I found.
