The
PLUG1L
(
Plug Into Port 1 Lower Half
) function is identical to the
PLUG1
function
except that it only operates on the lower half of Port 1 (Page 8 of the logical address
space). This function can only be used with module images that are one page long.
The
PLUG2L
(
Plug Into Port 2 Lower Half
) function operates on the lower half of Port 2
(Page A).
The
PLUG3L
(
Plug Into Port 3 Lower Half
) function operates on the lower half of Port 3
(Page C).
The
PLUG4L
(
Plug Into Port 4 Lower Half
) function operates on the lower half of Port 4
(Page E).
The
PLUGP
(
Plug Into Printer Page
) function operates on the page normally used for a
printer (Page 6). Do not plug a printer into the calculator if you have virtually plugged an
image into the Page 6. Page 6 is special in that the Operating System often calls printer
routines in this page. Normally, if no printer is plugged into the calculator the software
immediately returns to the Operating System without ill effect. So any image plugged into
Page 6 with the
PLUGP
function must keep these printer subroutine entry points clear so
that the Operating System can function properly. Only these images are known to be
compatible with Page 6:
