- Introduction
-
- The RAC Frequency Catalog program provides a convenient method
- of cataloging, retrieving, and printing frequencies for the SWL or
- scanner enthusiast. The program requires a IBM PC or compatible with
- 384K of memory and two floppy disks or a hard drive. (A hard drive is
- preferred for speed and database capacity.) Hard copy of the data can
- be obtained on any 80 column printer attached to LPT1 of the PC. The
- program is designed for a color monitor, however, a monochrome
- monitor will work fine too.
-
- The data files maintained by the RAC Catalog are compatible with
- Ashton-Tate's Dbase III+. This allows the user to access the RAC
- database files with Dbase III+.
-
- However, the index files used by the RAC Catalog are not compatible
- with Dbase, so users must use caution when modifying the databases.
- The report format is controlled by a Dbase compatible .FRM file.
- This also allows the user to create customized reports by modifying
- the report form with Dbase III+.
-
- RAC Catalog will maintain any number of database files. This allows
- users of floppy disk systems to break up their data records to files
- sizes that are compatible with the limited storage of floppy disks.
- Also, data can be organized in sub-groups such as by state, type of
- users, source of the data, however the user would decide to organize
- his data.
-
- A note on Shareware - Shareware is a concept for reducing the cost of
- software. It is NOT freeware! Use this program, give copies to your
- friends, upload it to Bulletin Boards. If you find this program
- useful, become a registered user by sending $25 to the address below.
- In this way you support the cost of developing and maintaining the
- software. All registered users will be sent up dates to the program
- as they are issued.

- Files
-
- The following files are included on the disk (or in the .ZIP file)
- and are required for operation of the system:
-
-
- FREQS.EXE Executable program file.
-
- FREQ1.FRM Dbase III+ compatible report form.
-
- FREQS.DBF A database of databases. Contains an entry
- for each different database to be serviced by
- RAC Catalog.
-
- MAIN.DBF Sample database.
-
- FREQS.DOC This file.
-
-
-
- Start-up
-
- If you are using a system with a hard drive, create a directory for the
- frequency catalog program and copy all the files to that directory.
- Start the program by typing FREQS.
-
- For floppy disk systems, create a system disk by coping FREQS.EXE,
- FREQ1.FRM, and FREQS.DBF to a formatted system (bootable) disk and
- place it in drive a:. Copy MAIN.DBF to a formatted diskette and place
- it in drive b:. Additional databases should be created in drive b: when
- using floppy based systems.
-
- When operating with floppy drives, always put the database diskettes in
- drive b: and the program disk in drive a:. The diskette in drive b:
- must have enough space to hold the database and its index files. A single
- 360 Kb floppy will hold approximately 1000 records. If you have more data
- records than this, segment them into multiple files and store them on
- different floppy diskettes.
-
- Select the a: drive and run the program by typing FREQS. On start-up
- the program looks for the database file FREQS.DBF from which you will
- select the user database. If the program does not find FREQS.DBF it will
- prompt the operator for the drive and path to the file. If not found it
- that path, the program will abort.
-
- The first time the program is started it has to build the index files
- for the databases. This takes only a minute or so, depending on the
- size of the datafiles. Again, the indexes will be built on the floppy
- containing the database or in the directory containing the database if
- used on a hard drive system.
-
- NOTE: The database files are Dbase III+ compatible, the index files
- are NOT! You may access the database files with Dbase III+
- however if any of the Key Fields (User, Frequency, or Service Code)
- are modified the RAC Catalog index files will be corrupted.
- This causes no significant problem, just delete the index files
- (.NTX extension) and restart the RAC Catalog Program, it
- will rebuild the indexes. If you experience any unusual display
- operation, the indexes should be deleted and re-built by restarting
- the program.
-
-
- Main Screen
-
- On start-up the program will display the shareware notice and then go
- to the database selection screen. The program can use any number of
- databases in order to allow the user to segment his data anyway that
- he desires. A sample database has been provided. You may create
- your own by pressing <Esc> and following the prompts.
-
- After database selection the program goes to the main display screen.
- All functions are accessible from this screen. The main menu can be
- accessed by pressing the "M" key. Selecting a menu function is as easy
- as using the arrows to move the highlight to the desired operation,
- and press the <Enter> key.
-
- You may also press the first letter of the desired function from the
- main display screen (except S - Select new database) without calling
- up the main menu. For instance to change the display order press O,
- the select menu for the display order will appear.
-
- Cursor movement from field to field can be accomplished by using the
- RightArrow and LeftArrow keys. Holding down the <Ctrl> key with the
- Arrow keys will scroll the screen one entire window. Vertical scrolling
- from record to record is accomplished with the DownArrow and UpArrow keys.
- Paging of the data records vertically is done by pressing the Pg Up and
- Pg Dn keys.
-
- Unlike Dbase III+ browse, pressing a key will not modify data on this
- main display screen. You may modify a field from the screen by moving the
- highlight to the desired field and pressing the <Enter> key. You will note
- that a cursor appears to indicate the edit mode. Make the desired changes
- and press <Enter> again to complete the modification and save the changed
- record.
-
- Main Menu Functions
-
- Pressing the "M" key will pop up the main menu. All functions of the
- RAC Catalog program are accessible from the main menu. You may press the
- first letter of the desired item, or move the highlight with the Uparrow and
- Downarrow keys and press <Enter>. A short explanation of each function is
- displayed across the bottom of the screen as the highlight is moved. As you
- become familiar with the functions you may access them directly from the
- display screen by pressing the first letter of the name of the function.
-
- The functions are as follows:
-
- Add Adds records to the currently selected and displayed database
- file. The add record function will pop up a small window
- that allows full screen editing of the record. Pressing the
- <F3> key on a field entry will recall the data entered in
- that field for the previous record.
-
- Delete Deletes the currently highlighted record from the database. The
- record is marked for deletion, and it database will be packed
- when a new database is selected or the program is exited.
-
- Edit Edit the currently selected record in a pop up window. This mode
- is different from the single field edit mode on the main screen
- in that you can see the entire record in the pop up window. You
- may also edit a field within a record on the main screen by
- pressing the <Enter> key on the field. You will see the
- cursor appear to indicate the edit mode. Terminate the edit
- by pressing <Enter> again.
-
- Find Allows seeking a specific record in the database. Find is
- dependant on the display mode. If the display order is set to
- "User" order, a prompt will appear at the bottom of the screen
- asking for the first 8 characters of the user. If the display
- modes is set to "Frequency," the prompt will ask for the frequency.
- If in the "Service Code" display mode, the prompt will ask for the
- two character Service Code. In all cases, if the exact match is not
- found, the program will position the highlight to the nearest record
- past the desired match. Note that this is an ASCII search, and
- that upper case characters will come before lower case.
-
- Order Selects one of three display orders, by Frequency, by User
- name (the first eight characters of the user name), or by
- Service Code. In User and Service Code modes, the display is
- secondarily ordered by frequency.
-
- Print Selects print menu. Printer support is for a 80 character
- width generic printer, no control codes are sent. You should
- select the printer modes before starting the Frequency
- program. Make sure you printer is on line, or the program
- will exit.
-
-
- Creating Database Files
-
- As pointed out previously, the program can support any number of database
- files allowing the user to segment a very large collection of frequency info
- into files of manageable size or to allow them to be stored on floppy
- diskettes.
-
- To create a new database, from the main display screen (or from the database
- selection window at start-up) press the "M" key to pop up the main menu, then
- "S" to bring up the database selection window. To create the new database
- file press the <Esc> key. You will be prompted for a seven character name
- for the database file, and the notation for the selection display. After
- entering this information you will be prompted for the drive and path on which
- to create the new database file. This should be a valid DOS drive and path
- specifier and should always end with the backslash character "\"
-
- The program will create the database file, build the three index files
- and go to the main display screen. Of course there will be no data
- records to display. You may then begin entering the data.
-
- From the database selection window you may also delete a database file.
- This is the same as with deleting a record from the main screen, pressing the
- "D" key on the highlighted record will allow deletion of the database from
- the selection window. NOTE: This action does not delete the actual data
- file, but rather the reference to it in the FREQS.DBF file.
-
- If during the creation of a database you attempt to create a file that
- already exists, the program will indicate that a file already exists and
- ask if you wish to use it. This is useful if someone gives you a compatible
- database and you would like to add it to your database selections. Answer
- "Y" and the program will add the new database to the selection window and
- build the indexes for the new file.
