Microprocessor – 8085 Instruction Sets
Note that 56h is actually considered to be a hex constant. Constant addresses should be used with caution. But in that I can see only the last solution, since solutions are overwritten by subsequent ones.
In my system, it took almost 1 minute gnusiim8085 computer all the solutions. Anything after ; is ignored by the assembler, except to one important character sequence It can be used to give names only to numeric constants. Thats all for now folks! DB is used to define space for an array of values specified by comma seperated list. There are example programs in the docs section, which you can get used to!
Comments start with a semi-colon. Auto breakpoints As you get acquainted with the application, you can use breakpoints to debug your program. Unless otherwise specified, a constant which is always numberic is in decimal form.

Final notes Don’t forget to include the HLT instruction somewhere else in the program to terminate it, otherwise you will be fooled! As you can see in the previous example, comments can be given to any part of the program. Here finding tutoriwl the solutions for say 8 queens is time consuming it involves a total of 92 solutions.
After all, I am using my spare time to do all these things.
GNUSim – Wikipedia
Now I can give a breakpoint at the place where the program finds the next solution. If a hex tutoiral starts with an alpha-char don’t forget to include the number 0 in the begining, since that will help the assembler to differentiate between a label and a constant. As you get acquainted with the application, you can use breakpoints to debug your program.
And the label if given to the begining of DB is assigned the address of the first data item. Comments Comments start with a semi-colon.
Pseudo Ops There are only 3 directives currently available in our assembly language. When the breakpoint is reached, I can stop and see the solution by examining the variables and then continue for the next solution.
Labels must always be placed in the first column and must be followed by an instruction no empty line. But don’t get upset!
Nesting of EQU is not allowed. But it is simple. This can be automated.
In addition, you have constants in an assembly program. A perfect example for this is the N-Queens problem. If ; is encountered, the editor will set breakpoint in the next line.
And this comment should start at first column. But for certain programs, you have to display something to the user before continuing. Then it takes the operand of EQU as its value. You can refer many available text books on programming for this.
Mnemonics After all, I am using my spare time to do all these things.
