In FTN95, I found that on exit from DO 10 I=1,3 that I was 4, which is not undefined, but is defined in a way that is relatively useless. Integers can't be undefined in the way that REALs can. As for ...

John,

No I'm not the best person As , but what you describe is a side effect of IMPLICIT NONE. The scoping rules used to be simple:

Global - subroutine and function names, intrinsics, named comm ...

The scoping rules are plain for the case you request, and have, as far as I know, always been so. The scope of a loop index variable in (say) a DATA statement is local to the statement (as it can be d ...

Is a CONTAINS routine put in-line like a statement function, or is it the same as any other subprogram apart from scoping?

Calm down, Dan! You don't have to - well, at least not currently. But if you wanted to, you don't have to do it all at once. And if the Fortran Committee dictate, maybe you'll have to. As for me, I'll ...

Precisely, John. The issue of how you name your variables of different types is separate from whether or not you use IMPLICIT NONE or not, and as well as incrementally incorporating IMPLICIT NONE in y ...

I agree that it is desirable that it should be all or nothing as far as IMPLICIT NONE is concerned, the point was that if you want it, it is possible to implement it routine-by-routine AND still keep ...

Dan,

I'm not a fan of IMPLICIT NONE either, but there is no constraint on variable names, and even with IMPLICIT NONE you can declare all your INTEGERs with names that start with ijklmn if you choo ...

I can not imagine that MIN or or WINDOW_UPDATE@ can be defined differently for any reason.

Well, MIN could really be MINI or MINE or somesuch accidentally edited, although I at first suspect ...

Ryan,

If you understood OpenGL, you will certainly understand %gr, as the difference in complexity is like reading War and Peace (in the original Russian) compared to a nursery rhyme.

Paul,

I don't think Moorthy's message is at all cryptic, but the comment was directed at some of the other the 193 messages (and the ones not listed). What about:

Dan,

If I copy your code, insert a PROGRAM statement, and put a tab instead of spaces before j=, then I get '... does not allow ...' for both i and j. With WIDE_SOURCE I get '... accepts ...' for b ...
