AGILE 5250 OPTIMA User’s Guide and ReferencePage 4-4
Decimal  Prints out the parameter value in decimal (base 10). To use
this format, the user must have the character code translation
table for the OPTIMA set correctly.
Byte  One byte. It cannot send a value greater than 255.
HiLoWord  A two-byte word in which the high-order byte precedes the
low-order byte.
LoHiWord  A two-byte word in which the low-order byte precedes the
high-order byte.
Hex  Prints the parameter value in hexadecimal (base 16). To use
this format, the user must have the character code translation
table for the OPTIMA set correctly.
GFIDs
IBM systems refer to fonts using numbers from 00001 to 65534. These
numbers are called GFIDs, or global font identifiers. (Sometimes they are
referred to as font identifiers, FIDs or typestyle numbers.)
The System selects a particular font by sending a GFID request to the
printer. The OPTIMA takes the GFID request and translates it into an
escape sequence that the printer will use to select a font. The escape
sequence that a particular GFID evokes is determined by two tables used
by the OPTIMA. The Portrait Font Correspondence Table (PORT ID>)
contains the escape sequences for portrait oriented fonts, and the
Landscape Font Correspondence Table (LAND ID>) is used for landscape
oriented fonts.
If the printer is listed among the supported configurations, the font
correspondence tables will be loaded with the rest of the configuration.
The fonts evoked by the escape sequences in the correspondence tables for
the printer will approximate those evoked by the IBM GFIDs as closely as
possible using the fonts readily available for the printer.

User Font Configuration

To edit an existing GFID, move through the configuration menu to the
appropriate output port, load a supported printer configuration, then find
FNTINFO:. Press g, then use d and f to select either PORT ID> or
LAND ID>. Press g again, and the user will be in GFID edit mode.
