- PowerBasic Directory Function: Version 1.05 November 24, 1990
-
-
- What is the program:
-
- The files in this archive use the Directory function of PowerBasic
- 2.10. I have added a sub-routine to read a directory along with
- additional information about each file in that directory.
-
-
- How it works:
-
- The heart of the program is the 'DIR$' function included in the
- PowerBasic 2.10 package. I used this as the base for the GetDirectory
- functions. When I ran a test call to get the 'DTA' after doing a
- 'DIR$' I found that the DTA area had all of the additional information
- about the file. Using this fact I wrote a sub-routine to get a
- complete directory.
-
- The sub-routine in 'TTDIR100.BAS' is the first draft of this
- sub-routine. All of the information about the directory is stored in a
- string array.
-
- The sub-routine in 'TTDIR101.BAS' is the second draft. I corrected a
- problem in calculating the size of the file. Also, I found out that I
- could place the call to get the 'DTA' outside of the loop reading the
- directory.
-
- The sub-routine in 'TTDIR105.BAS' is the latest draft. I placed all
- text information into one string array. Also, I moved the file date
- and time into a separate integer array and the file size into a third
- separate array. I did this to see if using integer arrays were faster
- than appending everything into a string array. There should be a
- program called 'TTEST5.BAS' that will call all of the sub-routines to
- show the difference in speed.
-
- If you don't have PowerBasic you still can use these program. Just
- replace the first call to 'DIR$' with the DOS 'FINDFIRST' function and
- the second call to 'DIR$' with the DOS 'FINDNEXT' function.
-
- The sub-routines themselves have comments on the parameters expected.
- If you have any questions, comments, for suggestions on this subroutine
- you can reach me on CompuServe. My ID is 72540,2315.
