Page B-15APPENDIX B — SCS/DCA COMMAND SUMMARY
Command: Set FID through GFID (SFG)
Format: 2B D1 nn 05 gfid fntw ps
Printers: 3812, 5219
Action: Selects the font and spacing used for subsequent text.
The gfid parameter specifies the Global Font ID (GFID)
or typestyle number to be used.
The fntw parameter divided by 1440 specifies the
character width in inches (Characters Per Inch equals
1440 divided by the fntw parameter).
For the 5219, the fntw parameter is restricted to 0060h
(15 CPI), 0078h (12 CPI) or 0090h (10 CPI). All other
values default to 0060h (10 CPI).
The ps parameter specifies whether monospacing (01h)
or proportional spacing (02h) is to be used. A value of
00h means no change.
For the 3812, both the fntw and the ps parameters are
discarded. The 3812 always uses the spacing for which
the font requested was designed.
IBMEMUL: Same as IBM.
When the OPTIMA receives this command, it selects a
font at the target printer in the following manner:
If Computer Output Reduction (COR) is active, and if
the CPI value selected by the fntw parameter is different
than the current setting, one of these PFSs is sent to the
target printer:
PFS: Condition:
COR 10> CPI = 10
COR 12> CPI = 12
COR 15> CPI > 12
For COR mode, these PFSs should select fonts 13, 15
and 20 CPI, respectively, to provide horizontal reduction.
If the orientation is COR, this is the only action
performed.
