nSelects USET character set number; enter a value ranging from 1 through 8.

ca

Represents the ASCII character cell hex address

 

which will have its contents replaced with the

 

character located in the font address (fa). The ca

 

value must be one of the 16 hex values specified in

 

Table 23 on page 255.

fa

Represents the hexadecimal value for the font

 

address of a specified character in the Multinational

 

character set which will replace the current

 

contents of ca. The fa value is the character

 

substitution for the cell address (ca). The value of

 

fa may range from 20 through FF hex.

END

Ends the USET command.

Comments You can define up to 16 character substitutions for each of the eight user-definable character sets. It is not necessary to address all 16 spaces available for character substitutions with a single USET command.

The character sets in the USET command are numbered 1 through 8. The character set values in the Character Set Selection (ISET) command (page 256) are numbered 24 through 31 and correspond to User Sets 1 through 8. The ISET command accesses and prints that custom character set.

The USET and ISET commands are related as shown in Table

23.Therefore, ISET;24 selects the substitution set defined as USET1, ISET;29 selects USET6, etc.
