Have you noticed that the Modula compiler 'modula.prg' will only run if it is put in the root directory of a drive 'd:'. It refuses to even startup if put in any sub-directory. The linker and editor work OK in subdirectories though. I guess it is due to the overlay directory, which also has to be in the root directory. On my hard disk this does not fit the usual \bin \src etc scheme of things. It is obvious that the designers never considered hierarchical file systems. The file dialogue are driving me crazy. Has anyone else got the error '- compiler error 2', while compiling a program. This is followed shortly with a dialog box saying 'Run Time error #9'. In the manual run time error #9 says 'Program Halt'. Any hints?? More questions: any answers will be much appreciated. Suppose we have TYPE word = ARRAY [1..15] of CHAR; VAR s1: word; s2: ARRAY[1..10] of word; .... and we write IF s1 = s2[i] THEN ^ operation with incompatible type (140) The Tdi compiler gives the above error, but the Powell m2 compiler does not object. Who is right? (reading Wirths or Thalmann's book didn't give me any answer). Also TYPE word= ARRAY [1..20] OF CHAR; .. PROCEDURE init(i:INTEGER; w:word); VAR x:word; ... x := w; .. END init; init(1,'Something '); (* 'twenty chars in string' *) ^ type incompatibility (128) gives the above error. if i change the type declaration to TYPE word = ARRAY [0..19] OF CHAR; The program compiles. Powells compiler of the Vax does not object to either Type declaration. Again who is right? I better stop before i break my '?' key. Any answers will be much appreciated. -- Jwahar R.

The compiler 'modula.prg' DOES run even if it is in a subdirectory (at least on my system). I have the developer's hard disk. One thing I've found out is that the compiler performs some checksum on the overlay files as they are loaded and it will give an error if the overlay files have been modified. The error number I got was 7 (?). Why would I want to modify the overlay files? Well in 'm2cpass1' are the keyword symbol tables. I modified it so that I could use lower case keywords. If anybody knows of or finds a way of disabling the case specific 'feature' of TDI's Modula-2 I would appreciate the help/info. - Robert Ling.
