Mel,
Thank You for your reply.
The programs in question are written for a 16 bit processor and
we need them to run in a 32 bit environment ( modern computer ). This to my understanding will lift the 640k limit.

My employer wrote and has been using his code for many years.
He has purchased Power Basic but would rather not have to
relearn Turbo Basic then learn Power Basic. He has chosen to buy
the talent needed to do this.

I am acting as a "gofer" in this matter. When I find someone who
can fulfill his request you will be talking to him directly.

Sorry to have made myself misunderstood.

Bill,
In order to use the BBS properly, reply to the same thread you started the discussion in.
As stated in the previous thread, DOS has an automatic limit of 640K, no matter which compiler you use. However, if you move to a Windows-based compiler, you get the addressing capability you seem to be seeking.
Nevertheless, all depends on the desire of the user. Is it your employer's wish to convert his code to Windows, or to continue with DOS?

regards,
Ian Cairns

Mr. Ian Carns:
I will try and describe the problem. We load the schedule of
parts to be made into memory. Schedule is an array of 64k and if
more than 220 items are posted in the program then an
" OUT OF MEMORY " problem exists.

The programs are all text NO GRAPHICS. I will quote from Power
Basic's advertisement. " Easily port DOS BASIC code to Win32
today " or " Access to the Win32 API ".
This to me means that the memory barriers get lifted.

To address your question of continuing in a dos window or
creating a full " Windows " application out of it. He would like
to remain in a dos window and alter his code from there.

I gather that the target compiler is the PowerBASIC Console Compiler,
not PB/DOS.

To keep a "DOS" looking window in Windows, today, you need PBCC,
and not PB 3.5 for DOS. DOS is DOS is DOS. In DOS, you' use EMS
but to fly under Windows, the Console is the way to go.
Quite easy port from DOS.

If you are running out of memory with TURBO BASIC, just upgrade to PB.DOS 3.5

TB had limits on array sizes which the current PB/DOS does not have. (Talk about an easier port!)

Or... Change that one big (64K) array to a random access disk file. This mod you can do in Turbo BASIC. Still easier IMO than porting to Windows.

If you want to look at either of these options, regardless I would check if you are truly "out of memory" or just exceeding TB's limits on array sizes.

This is true; However, it should be noted that PB/DOS allows
for data storage in all available base memory. Although I
haven't tried this in a windows environment, in a DOS 6.2
environment, I have had in excess of 400K of data in memory,
waiting to be processed. Of course, the bigger the program.....

Gentleman,
Mr. Mel Bishop has agreed to look over our source code.
He now has copies of the source code, compiled code and
console compiler used on the source code.

Thank you all for your help.

Bill
