Developper's Notes Addendum
New reason codes in routines
when IN: A=screen file reason and B=0,
OUT: BHL screen file address without moving them.
It was especially done for getting the screen file address.
- OS_NQ / NQ_Ain
OUT: BHL=app name and new BDE=DOR address
new reason $0B : is exactly DR_RD (09)
new reason $06 : ? (at $02 $A506)
new reason $02 : ? (at $07 $B25D)
The call level is incremented each time a system call is called within another.
That's why when you set the error handler from an application you call this
OS_ERH routine with a call level zero : A=0.
Never implemented routines
- DC_SCN is not implemented
- OS_SR / SR_CRM $06 : Card removal is not implemented
- OS_SR / SR_CIN $07 : Card insertion is not implemented
- Index, there is no bug for ZZZ application key : it is not implemented.
