On my palm I used two short inline procedures written by Philippe to implement Turbo Pascal's exit and halt. Of course they use Motorola instructions.

Can you tell me the corresponding ARM instructions.

The Motorola versions are:

procedure exit; inline($4e5e,$4e75);
procedure halt; inline($2c6d,32,$4e5e,$4e75);

Alternatively I suppose I could use goto + label at the end of the procedure or program.

 Of course, you can use a goto instruction, but the procedure halt that stops the program is predefined : procedure halt(output_code:integer);

 Thank you Philippe, I did not know that. For exit which terminates a procedure I would still need a goto, or I suppose I could define it as a function and use return.English (auto-detected) » English

 There is no easy way to define an "exit" procedure, even with inline assembler. I plan to add it in a future version. Waiting his time, you may try this :
procedure brol;
label 10;
    procedure exit;
    begin
      goto 10;
    end;
begin // of procedure brol
...

     exit; // anywhere
...

10:
end;

 Yes, Philippe, that is what I thought of doing, but I think I'll just use the goto instruction directly at the exit point.
