- "KALLCOST" by Pete Sipple
- Written for the Psion Series 3 & Series 3a (May 1994)
- =====================================================
-
-
-
- This procedure allows call costs to be calculated either during a phone call,
- or prior to making a call.
-
- Includes costs for Mercury Calls, BT Direct Dialled Chargecard Calls, Mercury
- Chargecard Calls and BT payphones, as well as standard BT charges.
-
- KallCost has been designed as a no-frills procedure, so's not to waste valuable
- RAM. If you feel that KallCost is missing a vital feature, please let me know.
-
-
-
-
-
- Series 3 and Series 3a versions
- ===============================
- From Version 6.1+, KALL will be able to run on either the Series 3, or on the
- Series 3a.
-
- The author wishes to extend his thanks to Sean Wright for his help with the
- Series 3a screen layout.
-
- You should run KALL3.OPO for the Series 3, or KALL3A.OPO for the Series 3a.
- These programs call KALL.PRG, which contains the main program.
-
- If required, KALL3.OPO / KALL3A.OPO can be renamed to KALL.OPO
-
-
-
- Files included with this release
- ================================
-
- KALL3.OPO For Series 3 (can be renamed to KALL.OPO if required)
- KALL3A.OPO For Series 3a (can be renamed to KALL.OPO if required)
- KALL.PRG The main program file (MUST be in \OPO\ directory)
- KALL.DAT Data file containing call rates (must be in \OPO\ directory)
- KALLCOST.TXT This text file
-
- A file called KALLDEF.ODB will be created in the \OPD\ directory (see below)
-
-
-
- Changes with Version 6.1
- ========================
- Version 6.0+ has drastic improvements to layout and data storage.
-
- Version 6.0+ now includes the option for users to change charge information
- without having to wait for a new release from me. The Set Rates option
- will allow you to change rates, as well as editing three International
- rates.
-
- Version 6.0+ fixes several bugs, including smoother transition of timebands at
- midnight, correct identification of Cheap/Weekend rates for local calls, and
- should run slightly faster.
-
- Version 6.0+ supports three international calls, which can be altered by user.
- USA, South Africa & Europe included as examples.
-
- Version 6.03+ allows users to specify a percentage discount, if their carrier
- offers a discount - such as one of the BT 'options'. A variable unit rate and
- character-per-second rate can now be specified.
-
- Version 6.05 now accuratly reports BT chargecard prices, and includes rates
- for Mercury Chargecard - also fixes some minor bugs.
-
- Version 6.1 fixes a few minor bugs and has been re-written to enable translation
- for the Series 3a
-
-
-
-
-
-
- Defaults File - KALLDEF.ODB
- ===========================
-
- The procedure creates a small "defaults" file called KALLDEF.ODB in the
- \OPD\ directory.
-
- * Note * The structure of KALLDEF.ODB has changed slightly since Version 5.6,
- and again since Version 6.03. - Existing default files will be overwritten, and
- you will be prompted for new defaults when you first run Ver 6.03 or above.
-
-
-
-
- Rates
- =====
- This release now include details of the new charges which came into effect
- on 9th March 1994, following the introduction of BT & Mercury's daytime tariff.
-
- I am waiting for clarification of how the new tariffs will affect payphones and
- chargecards. Until I hear otherwise, I am assuming that the Dec 93 rates still
- apply.
-
-
-
- International Calls
- ===================
- Basic provision has now been made for international calls. At the present time,
- the user will be required to enter the rates themselves. This is to save RAM.
- Once a rate has been entered once, it will be remembered for future calls.
- This will allow users to set up three frequently called country. Please Email
- me if you need a current rate. A major problem with International calls, is
- timebands. Most, but not all, international destinations from the UK have a
- Standard Rate (8am-8pm weekdays), with Cheap Rate (8pm-8am & weekends).
- This is not always the case, and should be considered before relying on the
- figures supplied by KallCost. Charges for Payphones/Chargecards have not
- been implemented at this stage.
-
-
-
-
- Modem Transfers
- ===============
- KALLCOST also includes a calculator for file transfers by MODEM. By selecting
- 'Modem' from the Calculate|Calculate dialog, a duration and cost will be
- displayed once a file size has been specified. A 'cps' (characters-per-second)
- rate must be specified in Setup|Values. A Zmodem transfer at 2400Baud gives
- a cps of 240.

- Disclaimer
- ========
- New releases are issued shortly after price changes from BT or Mercury. Please
- contact me if your release is out-of-date. Please note that I can accept no
- responsibility for any inaccuracies in charging information. Rates are constantly

- correct. Please let me know if you discover any problems, so that I can keep

- KALL.OPO is released into Public Domain, and I am not looking for any
- payment for this procedure. I am, however, interested to know whether you
- have found this procedure useful, and whether you have any suggesions for
- improvements. Please feel free to email me with comments!
