The template allows you to create many Boolean expressions, but there is no way to do the following actions:

• Negate an operand
• Group operands
• Specify AND or OR
• Specify an operand multiple times on one template
• Specify a range

To do any of this, you will need to enter an expression directly on the VIT Extraction Boolean Expression panel. Blanks are recommended between all operands and operators. Again, the length of the expression is limited to the input area provided. No syntax error checking is performed.

A sample free-form expression follows:

  AI* | (LOCK | E'PIU' & X'31':15 |
  GBL* & A'476C' - A'4800')

This example selects each VIT entry that is either AI1, AI2, or AI3, or fulfills at least one of the following criteria:

• LOCK option group (LKEX, LKSH, ULKA, UNLK)
• PIU entry with value hex 31 at offset 15
• GBLK or GBL2 entry with any address from X'0000476C' through X'00004800'
