Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────The Declare Option─────────────────────────────────────────────────────
 
     The declare option controls warnings about undeclared variables.
 
     Syntax: /4{Y | N}d
 
     When the declare option is enabled, the compiler generates a
     warning message at the first use of any variable that was not
     declared in a type statement.
 
     The /4Yd option enables the declare option, and /4Nd disables it.
     The declare option is disabled by default.
 
     Example
 
          FL /4Ybd *.FOR
 
     The example above compiles and links all source files with the
     default extension (.FOR) in the current working directory. The
     debug and declare options are both enabled.
