I use a dual processor Mac.  Mine is an old 640,  66mhz on both sides. The
ability to paste back and forth was a huge timesaver when it comes to porting.

Also, I suggest taking a look at Borland's Delphi.  It is built on their old
Turbo Pascal compliler, which is really quick.  I mean less than 30 seconds to
rebuild a direct port from the Mac.  Mac takes several minutes.  I found
(Perhaps because I have programmed in Pascal for 10 years) that FB could be
ported on the fly.  I did much of it by pasting a fn and then doing search and
replace.  Once you get used to the hang of Pascal's syntax and punctuation,
you can translate very quickly.  In a week or two I was drawing windows PG
style and hooking it all up.

I should say I have never seen VB 5.0 but if I were to use VB, just my
opinion, don't go with anything less than 5.  I talked to a VB programmer
about porting for me and with compression he was hoping to get the app
installer on two disks with VB 4.0  Delphi delivers a single .exe that does
not need dlls just to run a simple vertical app.  My installer is less than
400k.  Look at some of the downloads on aol or shareware sites and read about
how you will need vbrun (I think that is the name) such and such and if you
try to use the wrong vbrun the program won't work.  Windows installs are
tricky enough without needing to get all that in the right places.

Last, am I glad I ported?   Alas, sorry to say, very glad.  Sales about
getting close to 5 to 1, Win vs Mac.

Hope this helps,

George
