Re: Escape sequence in gm2

Neither Wirth's PIM Modula-2 nor ISO Modula-2 support backslash escape sequences.

Instead, octal literals suffixed with 'C' are used to denote character codes.

CONST TAB = 011C; (* '\t' *)
CONST NEWLINE = 012C; (* '\n' *)

then use ...


... and ...


The common standard libraries usually include a module ASCII with character code definitions.

PS: As an aside, most of the issues you raised in your various posts are addressed in our Modula-2 revision which I believe Gaius intended to support at some point in GM2. Unfortunately, due to circumstances that have to do with putting food on the table and having a roof over my head, i had to take time off from working on our own compiler ( for all of last year. With a bit of luck I might be able to get back to working on it this summer. Meanwhile, the classic dialects are all there is, even if somewhat outdated.

I searched the web many times but found nothing. In C we use a backsplash to represent newline, tab, backspace... but when I use ORD('\n'); in gm2 it always complain that the conststring must be have length 1, it means it only accept one character and doesn't understand the backsplash. Please help.
