- Declare symbolic constants used in program:
- File to look for
- Enter the directory where the search should start"
- (optional drive + directories). Press <ENTER> to begin
- the search in the root directory of the current drive.
- Starting directory
- Make the top level call (level 1) to begin the search:
- Delete all temporary files createde
- by the program.
- Search complete.
- ScanDir
- = SCANDIR
- This procedure recursively scans a directory for the=
- file name entered by the user.n
- NOTE: The SUB header doesn't use the STATIC keyword
- since this procedure needs a new set of variables
- each time it is invoked.d
- Now searching"
- Make a file specification for the temporary file:
- Get a directory listing of the current directory, and
- save it in the temporary file:
- Get the next available file number:
- Open the DIR listing file and scan it:
- Process the file, one line at a time:
- Get an entry from the DIR listing:m
- If entry is a file:
- If the FileSpec$ string matches, print entry and,
- exit this loop:
- If the entry is a directory, then make a recursive
- call to ScanDir with the new directory:
- Now searching"
- Scan on this DIR listing file is finished, so close it:
- MakeFileName
- = MAKEFILENAME$
- This procedure makes a file name from a root string
- ("TWH" - defined as a symbolic constant at the module
- level) and a number passed to it as an argument (Num).
- GetEntry
- = GETENTRY
- This procedure processes entry lines in a DIR listing
- saved to a file.r
- Loop until a valid entry or end-of-file (EOF) is read:=
- Get first character from the line for test:
- Entry or EOF found, decide which:
- Not EOF, either a file or a directory.:
- Build and return the entry name:d
- Test for extension and add to name if there is one:
- Determine the entry type, and return that
- value to the point where GetEntry$ was called:
- Directory
- Filec
-
