Just to bring this thread back onto VFP, the O/S had a built in ISAM (Index Sequential Access Method) built into it which closely resembled VFP Files and indexes. On top of this we built a high level language to manipulate the ISAM files which virtually has a one to one with the early Foxbase & DBASE products on a database level i.e seek, find, browse, insert, delete etc.
it was at that time that I decided that any language that I was to do development of desktop apps on would have to have these facilities built into it and some years after I discovered Dbase II and Foxplus which was like a gift from god!

The ability of a "program" to effectively "learn" by modifying itself. Self modifying code was a real memory saver and a real No-No for the newly invented programming standards wonks. A couple of years later I was put in charge of ... programming standards - and I made it a rule 'no self modifying code' - so a lass (yes there were female programmers in the neolithic!) whose program was at the memory limit *moved some code into the data area, modified it, and executed it there* - then defied me to rule it out of order <bg> bl**dy 'L - that took me back!
