20.2.1.5. SAR$ COM Packet Generation PROC (S$ARCOMPKT)
The PROC S$ARCOMPKT generates a COM packet and reserves space for an image
buffer, output text buffer, output attribute table, input text buffer, and input attribute
table. S$ARCOMPKT also calls the S$ARCOMDEF PROC, defining the COM packet
fields.
Calling Format
S$ARCOMPKT x-reg,b-reg,dispflg
The parameters for S$ARCOMPKT are the same as for the S$ARCOMDEF PROC
(see 20.2.1.4).
Returns
The S$ARCOMPKT PROC places values in the following fields of the COM packet:
SA$PKTVER SA$IMGBUF SA$IMGBUFL
SA$OTEXTBL SA$OATTRT SA$ITEXTB
SA$ITEXTB SA$ATTRT SA$IATTRTL
All other packet fields are set to default values.
The generated buffers and tables use the default lengths (see Table 20–4). The
following externalized labels are used to reference the buffers and tables:
SCIMGBUF Image buffer
SCOTEXTB Output text buffer
SCOATTRT Output attribute table
SCITEXTB Input text buffer
SCIATTRT Input attribute table
