The VGL 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 VGL 
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.

The I command can also be used for vertical positioning. Use the 
I command to skip to a new vertical position and print the data. 
Interrupt commands also can be included in a Vertical Duplication 
command sequence.

Like the Alphanumeric commands, the Interrupt command also 
enables extended graphics functions, if not already in an 
Extended Graphics sequence.

To complete the printing of all interrupted command sequences, 
use ^I000^- or no ^I command in the last command sequence. 
The last technique is used in the following example.

The following commands illustrate the interrupt function 
combined with form construction using tabs and various 
character parameters in normal resolution. The Free Format 
Enable command is also used.
