GL PRO is a multimedia engine. It is not for the faint of heart. There
is a fair amount of learning that goes along with using GL Pro to create multimedia
applications. One of the most powerful features is its scripting language. For most
applications you will probably only need to learn a few of the commands, but you will also
need some understanding of how these commands work within different operating
The manual that comes with GL PRO is amazing! In the first 8 pages it
gives detailed instructions on how to install the software, and then extensively covers
all the places you can go for any help you might need. I found the manual to be a great
reference, but thought I needed just a bit more help. There is a book available from Pallas Press written by Conrad R.
Brandt titled "GL PRO for Windows FOUNDATIONS" that comes with a special version
of GL PRO on CD. I found this book to be well worth the $38.00 US price. Conrad Brandt
goes into great tutorial detail in this book and had me understanding commands and
This is not software that will create an application that will run on
the Internet. However, it does provide accurate control of HTTP, FTP, and E-MAIL
services. It is software that will allow you to create a multimedia portfolio that
can be distributed to prospective clients. The engine is small enough that, depending on
what you include in your application, you may be able to distribute your application on a
floppy disk. The engine uses about 325K of disk space and you don't need external DLL's,
drivers, or other files.
With GL PRO aren't limited to the standard rectangular window, you can
create unique shapes for your interfaces.
Above is the main GL PRO script editor interface. This is where you
will be doing all your scripting. The GL PRO Player allows you to preview your work as you
write your script. This means you don't have to write the whole application before testing
to see if it is doing what you expect.
In the beginning of the GL PRO manual you get a hands on introduction
on how to start building scripts and your application. The manual gives you the script to
type in and then you can test it. The manual also explains, step by step, what each
command you have used in the examples does. If you follow through the manual, by the time
you get to the end you should have a good understanding of the GL PRO scripting language.
If you have done programming of some type before, GL PRO is going to be a snap. If you
have never done any programming before, a little patience goes a long way. Either way, if
you take the time, I know you'll be happy with the results. I am.
I mentioned above about the manual and a book to help with learning GL
PRO. The above screenshot shows the online help available from the software. This is
a very extensive help file and there shouldn't be any reason for most not to quickly and
easily learn from these help files, or find just exactly what you are looking for in the
way of help. If GL PRO can do it, it will be in the help file. I really liked the
way the help is set up. It was extremely easy to navigate to find just what I was

Head on over to the GL PRO site to order your free evaluation CD to see
just how powerful GL PRO is. The free evaluation copy includes the commercial demos on it
so you can see what others have done with GL PRO.
There is easier software out there to create multimedia applications
with, but you won't find one that gives you as much control over your multimedia
application as GL PRO.
