Notes

  • Static process handle is unique to each application. It follows slot number and application order in slot (1-31 for internal slot, 32-63 for slot 1, 64-95 for slot 2, 96-127 for slot 3, 128-255 for installed applications). Index handle is always 1, Pipedream handle is 3...
  • Dynamic process handle (PID equivalent) is unique to each suspended or running process (range 2-127, Index PID is always number 1).

Code Block
titleNQ_Voz ($861E), Application verifies running OZ version (OZ V4.5 and newer)
IN:
    A  = check OZ version required (for example $45 for OZ V4.5)
    BC = NQ_Voz
 
OUT, if call successful:
     Fc = 0
     Running OZ is equal to or higher than specified version

OUT, if call reported incompatible OZ ROM:
     Fc = 1
     A = RC_QUITVOZ ($67)$38), OZ version not compatible
 
Registers changed after return:
     A.BCDEHL/IXIY same
     .F....../.... different

Notes:

if If OS_Nq, NQ_Voz is used on OZ ROM's earlier than V4.5, a standard "Internal Error" popup window is displayed to prompt the user to press ESC (the NQ_Voz doesnt exist).

For OZ V4V5.5 0 and later a similar but more correct window is displayed with "This application requires OZ VX.Y or newer" message if the specified OZ release is newer than what is currently running. , the "OZ version not compatible" message is displayed as a fatal error using a OS_BYE with A unchanged if Fc = 1.
