Some computers from "back in the day" used to allow "blank" lines, effectively just a line number and a space, to separate structures in this way. S*BASIC doesn't allow this (spaces used for indenting code instead), so we use REMark or : after a line number to do this. Personally, I think the ':' statement is neater in a listing. I don't remember there being any "official" or "recommended" way of doing this. Back in the 1980s at some point I merely started using the ":" as a separator line between structures in my programs after seeing it in listings from Simon Goodwin and Tony Tebby. Good to be able to use both methods I guess.EmmBee wrote: Coming back on topic, about the REMarks In TMD2003’s factorising program: they are being used to highlight the start of definitions. Back in the day, many years ago, I also used to do this. Nowadays, however, the modern trend seems to be to have a single line with just one colon “:” to separate the definitions.
Would be really useful if changes to QLib were possible to accommodate what has been said about REMark statements with FOR loops etc. Don't use that myself, but have seen plenty of listings where it is used.
