Replace S by space, T by tab and N by a newline.

Generating whitespace in whitespace is not the most efficient thing in the world. Generating any kind of dynamic code requires significant bit-twiddling which, in a language without bitwise operations, would cause the code size to explode. Therefore, this program does not attempt to do something smart, instead opting for just translating the source program one to one. It disassembles to the following:

 early:
 call S
 call S
 call N
 start:
 push 0
 dup
 ichr
 get
 push 35
 sub

 jz hash
 push 24

 jz semi
