My solution for the repeated mouse interupts has been to only update after a minimum movement distance.

Alternatively, you could have a status variable, say "magnify_in_progress" and eith ...

Dan,

You did not show how arrays MagnifierArr and ImageArr are defined.

My minimum requirement is as arguments would be:
integer MagnifierArr(3, ixsizMag,iysizMag), ImageArr(3,hres,vres)
This ...

Dan,

The following code could run faster and clarify some integer division.
Is magnFactor real ?

subroutine Magnifier ( ihw_Magnifier, magnFactor, ix_mouse, iy_mouse, &

I may be saying what Robert said, but slightly differently, as for a 32 bit executable on Win 9 +, a valid memory address could be between 0 to about 3.7 GBytes.

There is potential for some of the ...

Kenny,

I find the combination of Fortran local, automatic and ALLOCATE arrays work well for me for /64. I limit my memory management to call by reference arrays, so do not use pointers or memory ad ...

This is my contribution to understanding memory allocation
module ELEM_DATA_BASE ! (minimal example)

integer*4 :: MXELEM = 0 ! maximum element number ...

It is worth remembering that VirtualAlloc allocates (or uses memory) at page size granularity. So an alloc of a few bytes takes a full 4K page

Robert, Your earlier statement that you provided inte ...

Kenny

Here is a sample but you will need a new clearwin64.dll because __open_heap and __close_heap are not currently exported.

I am interested in aligning ALLOCATE on a page boundary, so I am wo ...

If running the above program with task manager, show both "Commit size" and "Working Set"

Dan,

Without /UNDEF, this program will allocate successfully until the size of Arr4 exceeds your virtual memory size limit.
As you never access / "touch" Arr4, it will never be allocate ...

This looks to be a good approach.

I also use ftn95.cfg to include:
/SET_ERROR_LEVEL Warning 327
( I assume there can be multiple of these instructions in ftn95.cfg or multiple error numbers liste ...

Simon,

There are some approaches that might get around some of the problems you may have.
I have not needed extended derived types in my coding, while some allocatable components are acceptable.

Paul,

Thanks for these changes.

I think that /32 is a good addition, especially for clearer documenting of compile options in my .bat builds.

Also, my test from Fri Nov 18 did not identify & ...

Paul,

It is good to include in ISO_FORTRAN_ENV, those parameters that are relevant to FTN95 extensions for F03 and F08.

Just to clarify; I was checking if real80 or integer128 possibly might hav ...

Paul,

I was trying to locate what features had been added to iso_fortran_env but could not find any documentation.

I wrote the following program to see what might come out.

I noted:
