- (* for implementation the modules: *)
- (* Options and CompFile are imported *)
-
- (* prompt : string is displayed on terminal *)
- (* name : for construction of a default file name *)
- (* name of the module to be opened, i.e. for which
- a file name.ext, or LIB.name.ext must be found *)
- (* defext : default extension of searched file *)
- (* file : opened file (read-only mode) *)
- (* query : explicit asking for file name *)
- (* acceptdefault : accept a default file name *)
- (* acceptoptions : accept options appended to file name *)
- (* options are not evaluated *)
- (* acceptedfilename: final file name *)
- (* goodfile : lookup was successful *)
- (* nofile1 : operator said: omit this file *)
-
-
- PROCEDURE CreateFile (VAR prompt: ARRAY OF CHAR;
- VAR name : ARRAY OF CHAR;
- VAR newext: ARRAY OF CHAR;
- VAR file : File;
- query, acceptdefault, acceptoptions:BOOLEAN;
- VAR acceptedfilename: ARRAY OF CHAR;
- VAR goodfile: BOOLEAN; VAR nofile1: BOOLEAN);
-
- (* nearly the same as LookupFile. to open an output file with query*)
- (* doesnt try different libraries to create the file *)
- (* the extension is always changed to newext if default is TRUE *)
-
- PROCEDURE SetLibraries (VAR defaultlibstring: ARRAY OF CHAR;
- query, changedefault: BOOLEAN);
- (* set the libraries to be used in the searching strategy, and/or ask
- the user:
- defaultlibstring: 1 or more library names, separated by comma.
- or a full filename, from which the library name
- will be extracted (e.g. source file name).
- query : if the user should be asked for a libstring.
- changedefault : TRUE install 'defaultlibstring'.
- FALSE = ignore it, use the previous libstring *)

- END MCLookup.
