{{fbdoc item="desc"}}
Indicates if by default, string literals are processed for escape characters when not explicitly prefixed with the [[KeyPgOpPpNoescape|$ operator]] for non-escaped strings, or the [[KeyPgOpPpEscape|! operator]] for escaped strings.

The default method for processing string literals is set by usage of the //[[CompilerOptlang|-lang]]// command line option during compilation or usage of ##[[KeyPgOptionescape|Option Escape]]## in the source file.

##""__FB_OPTION_ESCAPE__""## returns zero (0) if the option has not been set. Returns non-zero (-1) if the option has been set.
