I'd like to do it step by step. First the syscall thing:

add an assembler file (with extension .src) to your SDK-project:

<code>
.SECTION P,CODE,ALIGN=4

.MACRO SYSCALL FUNO, SYSCALLNAME, TAIL=nop
.export \SYSCALLNAME'
\SYSCALLNAME'
mov.l #h'\FUNO, r0
mov.l #H'80010070, r2
jmp @r2
\TAIL'
.ENDM

SYSCALL 049A, _StartAnyApp
SYSCALL 09F5, _APP_Program
SYSCALL 0910, _KBD_PutKey
.end
</code>

interfaces for the header file

<code>
void APP_Program();
int StartAnyApp( int appno );
void KBD_PutKey( unsigned int keycode, int mode );
</code>

examples to start with:

APP_Program(); // should start the PRGM application (this works even with the emulator!)

StartAnyApp( 10 ); //starts the 10th application in the main menu (count starts at zero).

KBD_PutKey( KEY_CTRL_EXE, 0 ); // puts the EXE-key into the keybuffer

I hope this is something to start a bit experimenting.
