I've been playing around with the AAM instruction and came up with some
things you guys might find useful...

Strings as function results are WIERD with the inline Assembler. 8)
}

function div10(b : byte) : byte; assembler;
asm
  mov al, b
  aam
  mov al, ah
end;

function mod10(b : byte) : byte; assembler;
asm
  mov al, b
  aam
end;

type
  str2 = string[2];
  str8 = string[8];

function toStr2(b : byte) : str2; assembler;
asm {only call with b=0~99}
  les  di, @RESULT
  cld
  mov  al, 2
  stosb
  mov  al, b
  aam
  xchg ah, al
  add  ax, $3030
  stosw
end;

{makes date string in MM/DD/YY format from m,d,y}
function toDateStr(m,d,y:byte):str8;assembler;asm {only call with m,d,y=0~99}
  les  di, @RESULT
  cld
  mov  al, 8
  stosb
  mov  al, m
  aam
  xchg ah, al
  add  ax, $3030
  stosw
  mov  al, '/'
  stosb
  mov  al, d
  aam
  xchg ah, al
  add  ax, $3030
  stosw
  mov  al, '/'
  stosb
  mov  al, y
  aam
  xchg ah, al
  add  ax, $3030
  stosw
end;
