BIT PATTERN
Syntax:
!% BIT PATTERN [:] [:] <symbol> !% BIT PATTERN [:] [:] <string>
Function:
Specifies that the named variable is a foreign data type. fpt uses this information in constructing code to capture the variable when INSERT RECORD / REPLAY is specified. The named objects are handled as arrays of type INTEGER*1 or BYTE.
Names which contain exotic characters such as '%', ':' or '#' (which are all legal on some systems) must be written as quoted strings.
The % BIT PATTERN command must be written in code within the scope of declaration of the variable.

Default
Variables are not treated as bit patterns by default.
