Using the Pattern Generator
Building Test Vectors and Functions
When deleting vector rows, the INIT START, INIT END, MAIN START, 
and MAIN END cannot be deleted. Deleting all the vector rows from 
INIT START to MAIN END will reset the sequence to the powerup 
state. The deletion will not be performed if the results of the delete 
operation will place fewer than two vectors in the main sequence, or, if 
the delete operation will place an instruction on any of the following 
vectors:
• The first vector of the INIT sequence.
• The first vector of the MAIN sequence.
• The last vector of the MAIN sequence.
• The vector prior to the IF block.
• The first vector of the IF block.
• The last vector of the IF block.
• The vector following the IF block.
Merge
Selecting the Merge field brings up a pop-up menu that lets you select 
sections of a previously created configuration file to merge after the 
current line in the sequence. The Input Drive field selects between the 
hard disk or the front floppy disk (if present). The Filename field 
displays a file browser pop-up menu that allows searching for the file to 
be used in the merge. The Merge Section field lets you select the 
section of the configuration to be merged. Configuration sections 
consist of the main sequence and any functions that were created. The 
merge will not be performed in the following cases:
• Merge data exceeds the maximum number of sequence lines.
• Merge data requires more repeats than are available.
• Merge data requires more function calls than are available.
