Actually, that code won't work if the 68K compiler aligned the char
array on a 2-byte boundary, something that's quite possible because
the stack is only kept 2-byte aligned. Declaring that byte array as a
global would be the safest bet.

ok then this

0xF1, 0x91, 0xE5};
PceNativeCall(code,enable);
}
call it with enable set to "true" to enable writes, "false" to disable
writes to data area.
this is GUARANTEED to work on all current palmos devices (tested)
in case you're wondering the arm code is as follows:
MOV R0,R1
LDR R1,[R9,#-4]
LDR PC,[R1,#0x14C]
