Extended Mode Interface to SYSLIB
EM$EDIT returns the status of the call to AEDIT$ routines in the packet field CALLSTAT.
The CALLSTAT field is S3 of word 2 of the packet (packet address + 1). The possible
status are:
0 Normal return from the AEDIT$ routine
1 Error return from AEDIT$ (for function code 27 only)
2 Illegal value given for the AEDIT$ function code
EM$EDIT constructs the ASCII image in a buffer contained in the packet generated by
EM$EDITPKT. The address of the first word of the buffer is identified by the
externalized label EM$EDITBUF. The value of EM$EDITBUF is the offset from zero to
the start of the buffer.
Packet Generation
The EM$EDITPKT PROC generates the packet for the Extended Mode interface to the
AEDIT$ routines. This packet is required by the EM$EDIT PROC.
Calling Sequence:
label EM$EDITPKT buflen ['MSG', msg][ 'FPS', fps] :
['FPR', fpr] ['DPC',dpc] ['SPC', spc] :
['DFT', dft] ['TFT',tft] ['SEP', sep]
where:
buflen
The length in words of the data area used to contain the image constructed by
AEDIT$ This buffer is part of the EM$EDITPKT, and the address of the first word is
identified by the label EM$EDITBUF.
msg, fps, fpr, dpc, spc, dft, tft, sep
Optional parameters, as defined in Section 4.
I.3. Interface to BSP$
All of the functions of the BSP$ routine are called with the EM$BSP PROC. The packet
for BSP$ is generated with the EM$BSPPKT PROC.
Calling Sequence:
EM$BSP pkt, b-reg [func,param1,param2]
where:
pkt
The label (18-bit offset from zero) of the packet generated by the EM$BSPPKT
PROC.
