Chapter 2 Command Codes

Interrupt

Purpose In cases where a single command sequence exceeds the buffer

capacity, an interrupt can be used to break the command

sequence and specify the position where the sequence begins

printing again.

Mode Graphics with or without an Extended Graphics Command

selected

Format (cc) I

dis

(cc)-

(cc) Represents the Special Function Control Code

(SFCC). Enter the specific SFCC for your Code V

configuration.

I Specifies the Interrupt command. Enter I.

dis

Defines the interrupt position in tenth inches and

dot columns. Enter a two-digit interrupt position

value ranging from 00 through 99 to define a

position of 0.0 through 9.9 inches. Add a third digit

ranging from 0 through 9 to specify additional dot

columns. The Code V automatically understands

the decimal between the first and second digits for

tenth inches and automatically interprets the third

digit as dot columns. For example, entering 126

specifies a 1.2-inch plus 6-dot column interrupt

position. Setting the interrupt position parameter to

all zeros processes all data in the Code V buffer

before the next sequence is initiated.

(cc)- Graphics Mode CR used as a command terminator.

Enter the SFCC for your Code V configuration

immediately followed by - to end the command

sequence. (Note: Only required outside of an

Extended Graphics sequence.)

Comments The Code V buffer holds and can process approximately 64K

characters in a single graphics command sequence, which is

sufficient for most applications. However, infrequent situations

may arise where the command sequence is too large for the

Code V buffer to hold for processing as a single command

sequence. In such cases, use the I command to break the

printing command sequence at a specified position and specify

where the sequence resumes printing. Interrupted command

sequences are processed as if a single command sequence

occurred.
