SAR$ COM
20.2.1.2. Optional Information for SAR$ COM Procedure
The calling program may optionally set the following fields of the COM packet. The
default values are obtained by zero-filling the SAR$ COM packet before placing any
information in the packet.
SC$OCHART
The character set type of the image written out by the SAR$ COM function:
0 ASCII/ISO 9-bit characters (default), including all ASCII-like types in Table H–1.
1 Attributed character data (ACD).
Other character set types may not be written out by the SAR$ COM. See 18.3 for
details on the allowed output character set types.
SC$IMGBUF
The address of the image buffer; this buffer is necessary if either the output or input
character set types are ASCII/ISO with embedded shift-coded kanji or ACD. The
default is no image buffer.
SC$IMGBUFL
The length in words of the image buffer; a length must be specified if an address is
given in SC$IMGBUF. A length of zero indicates there is no image buffer (default).
SC$OATTRT
The address of the output attribute table, which contains the attributes that describe
the character text of the image that the SAR$ COM function writes out. If there are
no attributes for the output image, this table is not necessary. The default is no
output attribute table.
SC$OATTRTL
The number of valid entries in the attribute table. (Each entry is one word.) A value
of zero indicates that there is no output attribute table (default).
SC$IATTRT
The address of the input attribute table, which contains the attributes that describe
the character text of the image that the SAR$ COM function reads in. If the input
image does not have any attributes, this table is not necessary. The default is no
input attribute table.
SC$IATTRTL
The length in words of the input attribute table. A length of zero indicates that there
is no input attribute table (default).
