the web version page does not exist

The web version URL mentioned on the home page of this project https://forge.codesys.com/download/tol,c2iec,code.git/example.html throws 404. Is there a different functional URL where I could try?

Unary operators are not working

Ingo — Mon, 06 Jul 2020 16:20:22 -0000

CODESYS doesn't like the brackets around unary operators when they are not used within another expression. So, while this works: ~~~ i = ++i; i := (i:=i+1); ~~~ This doesn't: ~~~ ++i; (i:=i+1); ~~~ It's even worse for i++, as I was using a trick there to decrement the resulting value after the expression, which is sadly not possible. Full example: ~~~ int i; int a() { i = ++i; i++; ++i; } ~~~

IF statement is missing a THEN

~~~ int i; int a() { if (i < 0) return; } ~~~ results in: ~~~ i: DINT; FUNCTION a:DINT; IF i < 0 RETURN; END_IF ~~~ The "THEN" keyword is missing after the if-expression.

invalid syntax in the conversion of for-loops

Ingo — Tue, 30 Jun 2020 14:24:13 -0000

~~~ int i; int a() { for(i = 0; i < 2; i++) return; } ~~~ results in: ~~~ i: DINT; FUNCTION a:DINT; i := 0; WHILE i < 2; DO RETURN; ((i:=i+1)-1); END_WHILE ~~~ The semicolon after the while expression is invalid.
