- * Arguments supports access to user supplied program arguments. These
- * are command line arguments or workbench arguments depending on the
- * program activation.
- * If an argument comes with len=0 and its number is valid
- * ( 1 <= nr <= NumArgs() ) then it specifies the current directory.
- *)
-
- VAR
- (*
- * quoted indicates that the last argument contained quotes
- *)
- quoted: BOOLEAN;
-
- (*
- * NumArgs returns the number of arguments available.
- *)
- PROCEDURE NumArgs(): INTEGER;
-
- (*
- * GetArg returns the i-th argument from the argument list. If the program
- * is started from CLI the command line is parsed. Quotes are interpreted
- * slightly different as from DOS commands or C-startup code. All text
- * between two quotes is taken literally. Quotes may occur at any position
- * in an argument (see example). With workbench startup GetArg changes the
- * directory (CurrentDir) to the directory of the requested argument and
- * returns the argument name. GetArg(0...) returns the name of the currently
- * executed program.
- *
- * Examples for CLI Arguments:
- *
- * 1> command "Hello World"
- * 1> command Hello" "World
- * 1> command Hell"o World"
- *
- * All these calls give >Hello World< as argument.
- *)

- (*
- * sometimes it is useful to get the directory lock associated with the
- * arguments directory. Works only if started from WB
