TEXT REGISTER MACHINE IN APL ──────────────────────────── The TRM workspace contains an interpreter for the 1# language by Larry Moss. It is designed to be a simple, illustrative interpreter demonstrating both the simplicty of 1# as well as the elegance of APL. Launching the workspace, you can then run a 1# program by using the following EVAL: R←N EVAL P Here N is the register state, P is the program text, consisting only of spaces, 1's, and #'s, and R is the return result, which is the machine state (register state) at the end of the computation. If you want to start with a simple empty register state of M empty registers, you can do something like this: (M⍴⊂⍬)EVAL P Otherwise each element of N should be a character vector of 1's and #'s. You can see a nicer printed representation of a register machine state by using the PRINT∆TRM function on a register state.
