Lawrow and compatible with all the Atari 8-bit computers of that time.There was demand at that time to introduce a better Assembly language editor, so this one was met with great acceptance and would eventually become the premiere editor whenever someone needed to write an extension program in assembly language.Learn more about your Atari 65xe Hardware and the physical computer.
This allows the ability to track errors in your program, and even compression of source files. It is because of these amazing tools that this assembly language editor became a very common program to use by computer programmers (as they were known at the time). I had an excellent time learning the new commands such as REN (Renumber) and many other neat things. The debugger was called Dunions Debugging Tool or DDT for short. This allowed access to an see assembly language listing in memory. I personally recommend to use it and get an edge with your programming skills Back in the days, I had the privilege of creating a game called Deadman. I lost the originally disk files, but done a re-creation many years later during my early YouTube presence. Combine this with the conditional logic described earlier and you have some very powerful tools. Time spent just waiting for it to assemble a program could be put to much better use programming and debugging, or thinking of new program ideas. For any programmer who spends much time at all using the Atari cartridge assembler, the accumulation of wasted time could be so substantial it might actually be worthwhile for the programmer to rewrite the assembler to make it faster. For one thing, he would have the editor tokenize each source line, instead of storing it in AT ASCII format. This change alone would significantly increase the assembly speed, and would have three bonus side effects as well. First, with a tokenized format it would be possible to LOAD and SAVE source programs just as fast as Atari BASIC can LOAD and SAVE programs; there would no longer be any need to wait for the slower ENTER and LIST commands. The shorter, compacted files would LOAD in even less time, and take up even less disk space. And a condensed program size would make it possible to hold longer files in memory. With the addition of other improvements such as a faster symbol table search, the revised assembler would be extremely fast. If the programmer added some other features like powerful conditional logic, an alphabetized printing of the symbol table, local labels, and macro support, he would have created the best assembler available for the Atari. This offers users of MAC65 the added advantage of being able to use the same assembler on three of the most popular personal computers. The first is conditional assembly through the use of the directives.IF,.ELSE, and.ENDIF. Atari Emulator And 65 Code Is AssembledThe.IF directive evaluates an expression and controls how the following code is assembled. If the value is true (nonzero), only the code between the.IF and the.ELSE or.ENDIF is assembled. Should there exist a. ELSE (it is optional), the code between it and the.ENDIF will be assembled if the value is false. ![]() ![]() Whenever this label appears at any point in the source listing, the corresponding source lines will be inserted into the assembly. Note, however, that a macro differs in some ways from a subroutine; a macro only affects assembly, and since this example used the stack, SAVEREGS could certainly not be made into a subroutine (which stores a return address on the stack) without a stack conflict. One good example is the macro defined here to increment a 16-bit memory location. Another good example is the macro definition for OPEN, provided in the MAC65 manual. Once this macro has been defined, it is possible to have a source line which reads OPEN 3,4,0, D: FILENAME. This one source line will generate all the code necessary to perform an OPEN operation using channel 3, auxiliary bytes 4 and 0, and the specified filename. This takes a lot of the drudgery out of the tasks of writing in machine language. String parameters are indicated using a dollar sign, as in 1. ![]()
