Quite common in those days. Just a string composed of all the machine language code bytes, VarPtr used to find the address of the first byte and Call to execute it. Using Read/Data to poke the bytes into RAM was okay for 8 bit single-processing computers, but got a bit hairy under Windows (and you can't easily execute data space or write to executable space). Most computers (PC, Apple II, Commodore, etc.) had some implementation that allowed it.
All you need is an assembler to assemble the code.
The most difficult part of developing a program is understanding the problem.
The second most difficult part is deciding how you're going to solve the problem.
Actually writing the program (translating your solution into some computer language) is the easiest part.
Please indent your code and use [HIGHLIGHT="VB"] [/HIGHLIGHT] tags around it to make it easier to read.
