Take a look at the image below. The indent bar changes color, because I am entering a different nested group. Now, I have missed tricks similar to that in the past, DO's and END's all tie up in terms of numbers, but often I get blown away by a mismatch. What you have is a visual pre-compile check, that will not fix junk code, but will give the compiler a sporting chance. Get by with a little help.
Help is available on every turn.
I am not referring to application help, but more importantly, to help with SEU statements, OpCodes and syntax. But window based help is not all you get. Work in either 24x80 or 27x132 display mode Can be used in debug Where nested groups span more than one page, the learn feature can be used to keep track of starts and ends etc. Match Ends Delimit subroutines and procedures and a lot, lot more. Interestingly, there is no pre-processing of source.
