I just did a little disassembly now that i found out about the alt_ret
thingy.  I now understand how to use sqrtPARSE and make it work
correctly!  Here goes:

This is a sample sqrtPARSE program:

_alt_ret_status           equ         0D2F9h
_alt_ret_jmp_page         equ         0D2FAh
_alt_ret_jmp_addr         equ         0D2FBh

 ld a,$11
 ld (_alt_ret_status),a
 ld a,$3
 ld (_alt_ret_jmp_page),a    ;this could be combined with the 1st but i
didn't for clarity
 ld hl,$5851
 ld (_alt_ret_jmp_addr),hl
 ld hl,ParseIn
 rst 20h
 rst 10h
 ld a,b
 ex de,hl
   ;ahl now points to the parsed command-line.
   ;you can do whatever you want with this.
 ret    ;ret back to normal parser!

ParseIn:
.db $12,$01,"#"
