Operator ! (Escaped String Literal)operator

Explicitly indicates that a string literal should be processed for escape sequences.

Syntax

!"text"

Description

This operator explicitly indicates that the string literal following it (wrapped in double quotes) should be processed for escape sequences. This a preprocessor operator and can only be used with string literals at compile time.

The default behavior for string literals is that they not be processed for escape sequences. Option Escape can be used in the -lang fblite dialect to override this default behaviour causing all strings to be processed for escape sequences.

Use the $ Operator (Non-Escaped String Literal) operator to explicitly indicate that a string should not be processed for escape sequences.
