EXTREF Command
EXTREF {FONT lname | OB2CMR lname {AUDIT | INSTR | LINK} | OB2R [i2name | 'i2name' | C'i2name' | E'i2name' | A'i2name' X'hhhh'] OB2XNAME {x2name | 'x2name' | C'x2name' | E'x2name' | A'x2name' | X'hhhh' | U8'x2name' | U16'x2name ' | X8'hhhh' | X16'hhhh '} OB2ID {n | type-name}} ;
If an object contains another mapped object, the contained object must be mapped, but if the object is not known to PPFA, PPFA will not automatically map that object. The EXTREF command allows you to map unknown objects in the page.
For example, if you presented a GOCA object that contained a mapped font, CMR, and/or another object, those resources will not be mapped in the page. The EXTREF command can be used to map this required resource.
Note: Even though a font is mapped automatically by PPFA when it is used internally in the
page definition on a PRINTLINE, LAYOUT, XLAYOUT, or FIELD command, a font that is used in an included object, such as a GOCA object, is not
known to PPFA and consequently not mapped. In that case the user must define that
font with either a FONT or DOFONT command and map it with the EXTREF command.
