- PRINT'DIRECTORY 0.14
- by Phyrne Bacon
-
- The new PRINT'DIRECTORY prints the
- disk directory with or without the
- scratched files and the beginning
- track and sectors. The blocks free
- are read from the BAM; so that the
- "blocks free" number matches that
- given by cat. Scratched files are
- indicated by --- or 0 in the
- PRG-column.
-
- If the sum of the file lengths and
- the blocks free is not 664, the
- message pass"v" may free xx blocks is
- printed on the screen. If a file type
- number is non-standard, it is printed
- in parentheses in the PRG-column.
-
- A track/sector listing of
- PRINT'DIRECTORY can be used with
- DISK'EDITOR to unscratch files which
- haven't been overwritten: the article
- Disk Directories I: Unscratching
- Files. A DIRECTORY'PROBE listing
- indicates which files are the wrong
- length (and have been overwritten).
-
- A track/sector listing gives a
- directory listing with the
- track/sector of each directory block
- listed followed by the eight
- directory entries in that block and
- the beginning track/sector of each
- entry.
-
- A new machine language procedure is
- used in PRINT'DIRECTORY which reads a
- file thirty-two bytes at a time, and
- indicates the end-of-file by giving
- the number of bytes used in the final
- thirty-two bytes. Any type of file
- can be read by changing the open file
- 7 statement which is in COMAL.
