| Okay. I'm writing small programs for MirageOS. Is there a way to run a program for MirageOS, and exit MirageOS and display to the homescreen while running the program (without adverse side effects, such as explosive diarrhea)? |

you might try BCALL(_jForceCmdNoChar), but this ROM call is really meant to be called from within an APP. I'm not sure what it will do if called from within an assembly program that is run from an APP (and therefore outside of the normal page that APP code is on).
_JForceCmdNoChar EQU 4027h |

| _JForceCmdNoChar does exit MirageOS, but displays jumble on the home screen, even if you use ClrScrnFull before or after _JForceCmdNoChar. Also the program code after _JForceCmdNoChar does not seem to exectute. If you call _JForceCmdNoChar from a basic program (for the basic program to "bust out" of MirageOS), your Ram is reset. |

| of course the code after it doesn't execute; this ROM call is meant to exit APPs. It's essentially the same as a 'ret' at the end of an assembly program, but it does some cleanup for APPs. |

Why don't you make you're own homescreen, it's not that hard just:
bcall(_clrLCDfull)
ld hl,x*256+y
ld (currow),hl
ld (*pointer*),hl
bcall(_puts)
bcall(_getkey)... |

| And put that in every single program (he said small programs). Oh and in the pseudo-home screen, will I be able to go into the Y= Editor, type in sqrt(1-x^2), calculate the integral from 0 to .5 then go to the home screen to check which inverse function is the anti-derivative of Y1? Oh and while I'm there, type in "aaaaaaaaaaaaaaaa" into Y1, go into Calcsys and edit that to get some symbols for my Basic programs? Thought so. |

| In a word ... no. All _PutS does it write a string to the homescreen. |
