130 /* ------------------------------------------------------------------------- */

133 /* 4. Filenaming definitions: */
135 /* It's assumed that the host OS has the concept of subdirectories and */
136 /* has "pathnames", that is, filenames giving a chain of subdirectories */
137 /* divided by the FN_SEP (filename separator) character: e.g. for Unix */

140 /* White space is not allowed in filenames, and nor is the special */
141 /* character FN_ALT, which unless defined here will be a comma and will */
142 /* be used to separate alternative locations in a path variable. */
144 /* If NO_FILE_EXTENSIONS is undefined then the OS allows "file extensions" */
145 /* of 1 to 3 alphanumeric characters like ".txt" (for text files), ".z5" */
146 /* (for game files), etc., to indicate the file's type (and, crucially, */
147 /* regards the same filename but with different extensions -- e.g., */
148 /* "frog.amp" and "frog.lil" -- as being different names). */
149 /* (The file extensions defined below are widely accepted, so please use */
150 /* them unless there's a good reason why not.) */
152 /* You should then define STANDARD_DIRECTORIES (you can define it anyway) */
153 /* in which case Inform will expect by default that files are sorted out */
154 /* by being put into suitable directories (e.g., a "games" directory for */
157 /* If it's convenient for your port you can alter the detailed definitions */
158 /* which these broad settings make. Be careful if NO_FILE_EXTENSIONS */
159 /* is set without STANDARD_DIRECTORIES, as then Inform may */
160 /* overwrite its source with object code. */
162 /* 5. Filenames (or code related to filenames) for temporary files. */
163 /* These included Temporary_Name, Temporary_Directory, and */
164 /* INCLUDE_TASK_ID. These options have been removed, and are listed here */
165 /* only for people who might ask "what happened to 5?" */
167 /* 6. Any other definitions specific to the OS or machine. */
168 /* (In particular DEFAULT_ERROR_FORMAT is 0 on most machines and 1 on PCs; */
169 /* it controls the style of error messages, which is important for some */
170 /* error-throwback debugging tools.) */
