Logical Operations for String Fields in Rulers

In the string entry, .GE.40,000, the 40,000 identifies the actual search string and the .GE. identifies the logical search operation to perform, namely a "greater than or equal to" search.

In the previously specified string entry, search string 08 was specified without an operator. An equivalence check was performed (that is, report line strings were checked to see if they were equal to ruler-defined strings).

All "string-checking" edits (Color, Include, and Exclude) operate this way:

• Strings specified without operators are subject to equivalence checking.
• Logical operations (other than equal to) are indicated by typing .operator.string in the STR field.

Valid operations (and operators) are listed below:
