Thanks, I’ll post there tomorrow about the technical stuff. At first glance unless I totally underestimate something it appears to be a trivial extension to the define:= syntax but admittedly it’s edge case stuff and probably not widely used. I did a search and found only a few hits on the topic. Since I’ve been giving theoretical examples here’s something more practical a user attempted. Can you do that without macros? If I had to guess he had some funky code and just wanted to reduce typing and copy/paste bugs. {$define HOFFSET(rec,field) := pointer(@rec.field) - pointer(@rec)} type s1_t = record a: longint; b: single; c: double; end; var s1: s1_t; BEGIN s1.a := 12345; s1.b := 1.000000001; s1.c := 1.000000002; writeln(HOFFSET(s1, a)); END.
