Building a Brainfuck translator in TurboAssembler.
To begin with, we will write an interpreter in a high-level language, for example, in Pascal.
Let's write a program that outputs a character whose ascii-code corresponds to the number of +
Therefore, we only need the bf-commands + and .
var
data_mem: array[1..10] of integer; // data array
command_mem: string; // command array
i: integer; // index of command array
j: integer; // index of data array
begin
j:=1;
readln(command_mem);
for i:=1 to length(command_mem) do begin // in the cycle we process the string
if (command_mem[i]='+') then data_mem[j]:= data_mem[j]+1;
if (command_mem[i]='.') then write(chr(data_mem[j]));
end;
end.
bf-code +++++++++++++++++++++++++++++++++. will issue !
(the ascii-code of the symbol ! is 33).
The efficiency of the program can be checked in online ide ideone.com.
