- Introduction to WASP
- ====================
-
- WASP is a replacement for traditional printed Steam Tables, but it
- goes further in that it provides a much wider set of properties, it
- eliminates the need for interpolating between data points, and it
- will work in any of the generally accepted units.
-
- It contains data for 15 point properties, and 17 temperature and
- pressure dependent properties. Most of the correlations cover the
- range from -100 C to 800 C and up to 1000 bar, and some extend
- even beyond this range. Calculated data points match published
- data very closely.
-
- The programme has been carefully designed for speed and ease of use.
- On-screen prompts appear at every step to guide you. In addition
- there is context sensitive, on-line Help available at all times. If
- you are ever unsure of what the programme expects you to do, simply
- pressing the <F1> key will open a window with detailed instructions
- and information. You can also view any Help Screen at any time by
- selecting it from a Help Index.
-
- WASP is distributed as Shareware. If this copy is registered to
- anyone other than yourself, you are entitled to use it for a few
- weeks to determine its value to you. If you continue to use the
- programme then you must register your copy with Katmar Software.
- Further details on Shareware and the registration procedure are
- given later in this manual.
-
-
- Installation and Startup
- ========================
-
- You should not use the distribution disk that you received as a
- working disk. You should install the WASP package to either another
- diskette or to your hard disk.
-
- Installation of WASP entails simply copying all the files to either
- a diskette or to your hard disk. The distribution disk that you
- received should contain all of the following files :-
-
- GETRESP.EXE Utility for interactive batch files
- PAGE.COM Text file display utility
- README Brief details on WASP and its distribution
- README.BAT A batch file used to display or print README
- REGISTER.DOC Order form for registering your copy of WASP
- WASP.EXE The executable file for WASP
- WASPBOOK.DOC The instruction manual for the WASP package
- WASPDEFS.DTA Holds the selected units etc
- WASPHELP.HLP The on-line help instructions
-
- If instead of these files your disk contains a file named
- WASP101.ARC, WASP101.ZIP or some similar name then it means that the
- disk distributor has compressed the files into an archive file to
- get more onto the distribution disk. In this case you will need to
-
-
- Water and Steam Properties - Version 1.01 Page 1
-
-
-
- follow the distributors instructions on how to extract the files
- from the archive before you can copy them.
-
- If you are installing to your hard disk you should copy the files to
- a separate sub-directory. To create a new sub-directory on your
- hard drive follow these steps :-
-
- 1) Ensure that you are at the DOS prompt, ie display shows C:>
- (if your hard drive is drive D display shows D:> , etc)
- 2) If you want the new sub-directory to be off the root
- directory, type CD\ and press <ENTER>. If you prefer the
- new sub-directory to be off some other directory, change to
- that directory.
- 3) Type MD WASP and press <ENTER>.
- 4) Type CD WASP and press <ENTER>. Display should show
- C:\WASP>. If display does not show this, type PROMPT $P$G
- and press <ENTER>.
-
- If your distribution disk contains all the files listed above,
- insert it into the A drive and type COPY A:*.* and press <ENTER>.
- The programme is then ready to run. If your distribution disk does
- not contain all the files listed above, but instead contains an
- archived file, copy that file to the new sub-directory (eg COPY
- A:WASP101.ZIP). Then follow the distributors instructions to
- un-archive the files.
-
- Once the files have been copied you should type WASP and press
- <ENTER> to start the programme. The programme starts with an
- opening screen and then a screen giving brief details of the
- shareware distribution system, before getting to the programme
- proper. The initial screens can be skipped by pressing the
- <SPACE BAR>.
-
- If you are short of space on your hard disk you can delete some of
- the files. Only two files are absolutely essential for running
- WASP. These are WASP.EXE and WASPDEFS.DTA. If you want to be able
- to use the on-line help facility you will also need the file
- WASPHELP.HLP, but the programme can run without it. When you pass
- on copies of WASP to others please always include all the files on
- the distribution disk so that the recipient can make a full
- evaluation of the package.
-
-
- Hardware and Software Requirements
- ==================================
-
- WASP will run on virtually any IBM(tm) PC or compatible machine. It
- has been designed to be able to be used on a minimum specification
- system, but also to make use of higher specification equipment if
- available. For example it will run perfectly well on a monochrome
- screen, but will switch to colour if it detects a colour video card.
- Similarly it will use a numeric co-processor if it finds one, but
- will run quite happily (although of course more slowly) if none is
- found.
-
-
-
- Water and Steam Properties - Version 1.01 Page 2
-
-
-
- Some EGA and VGA displays, particularly on portable computers, use
- varying shades of grey rather than true colour. WASP would detect
- these machines as having colour screens and you may have some
- difficulty reading the display. In this case you can force the
- programme to use the monochrome palette by pressing <Alt M> at the
- opening screen or by using the /M command line switch i.e. start the
- programme by typing WASP /M. When you exit from the programme it
- will store this choice and start up in monochrome mode the next time
- you use it.
-
- Summary of system requirements :-
- DOS : 2.11 or later
- RAM : 512k or more
- DISK : 360k or larger floppy, stiffy or hard disk
- VIDEO : Monochrome, CGA, EGA, VGA or compatible
- Co-processor : Optional
-
-
- Quick Start for Experienced Users
- =================================
-
- Even if you are only a moderately experienced computer user you
- should be able to use WASP without going into this manual in any
- depth at all. The brief instructions that follow in this section
- should be all you need to make full use of the programme. The
- programme will guide you with on-screen prompts at every stage and
- on-line help is always available by pressing <F1>.
-
- The programme is started by typing WASP, or WASP /M if you want to
- force monochrome mode on a colour screen. The opening screens can
- be skipped by pressing the <SPACE BAR> or virtually any other key.
-
- After the opening screens you will see the DATA ENTRY screen. This
- is where you specify the conditions under which you want the
- physical properties calculated. In the general case you will enter
- the temperature and pressure, pressing <ENTER> after each entry.
- For the specific case of saturated conditions you need to enter
- either the temperature or the pressure, but not both. In this case
- you can use <TAB> to ensure that the property you want to enter is
- on the top line in the box and then key in the value. After typing
- the value, press <SPACE BAR> instead of <ENTER> and the programme
- will calculate the corresponding value for saturated conditions.
-
- During data entry the editing keys work in a very standard way, and
- should not give you any trouble at all. If there is already a value
- in the entry field you can accept it by pressing <ENTER> or <SPACE
- BAR>. If you want to enter a completely different value just start
- typing and the original value will disappear. However if the first
- key you press is an <ARROW> key the programme will assume you want
- to edit the displayed value and will not clear it.
-
- After you have specified the conditions the programme will calculate
- the properties and display them. There are two forms for the result
- screens. These are a brief and a full format screen. You can
- toggle between the two by pressing <F2>.
-
-
- Water and Steam Properties - Version 1.01 Page 3
-
-
-
- While either the DATA ENTRY or RESULT screen is displayed you can
- call up a list of fixed properties with the <F3> key. Pressing <F3>
- again will take you back to where you were.
-
- The units in which you specify the conditions, and in which the
- properties are displayed, can be changed with the <F4> key. The
- units can be selected in pre-defined sets, or individually if you
- want to mix systems of units.
-
-
- Printing the Manual
- ===================
-
- If you are reading this on your screen and you want to make a hard
- copy on your printer you can do it in one of two ways. The easiest
- way is to run the programme and then press <Alt P> at the opening
- screen. The other way is to type PRINT WASPBOOK.DOC at the DOS
- prompt.
-
-
- Detailed Operating Instructions
- ===============================
-
- This section gives full details for each step of using the
- programme.
-
-
- Start-up
- --------
-
- If you are running WASP from the DOS prompt (eg C:\>) it will be
- necessary to change to the directory into which you copied the
- files. You should then type WASP and press <ENTER> to start the
- programme. If you want to force a colour video card to display in
- monochrome you can start the programme with the WASP /M command. If
- you are using a hard disk manager or menu system all this should be
- automated into the menu.
-
- When the programme starts it will display the opening screen with
- the version and copyright information. After a while it will skip
- to the shareware distribution notice screen. Both of these screens
- can be skipped by pressing <SPACE BAR> or <ENTER>.
-
- If you have a colour video card but a monochrome screen, as is often
- the case with portable computers, you may have problems reading the
- screen. If this is the case, press <Alt M> to switch to the
- monochrome colour scheme.
-
-
- On-line Help System
- -------------------
-
- At any stage during the running of the programme you can press <F1>
- and get help on the specific item on which you are working. Once
- you are in the Help window you will see in the top right corner the
-
-
- Water and Steam Properties - Version 1.01 Page 4
-
-
-
- message "Page x of y". If there is more than one page of help
- available you can page through the help windows by pressing PgUp,
- PgDn, Home and End. The message in the bottom right corner tells
- you whether you can page up or down. There will also be flashing
- arrows on the right hand side that show if there is more data above
- or below the current page.
-
- If you press <F1> while a help screen is being displayed you will be
- shown an index of all the help available for this programme. From
- this index you can select any one of the help topics that are
- available. Simply use the <Arrow> and <Page> keys to highlight the
- topic on which you want help, and press <ENTER>.
-
- After you have read that help topic you can return to the Help Index
- by pressing <F1> again. You can switch back and forth like this as
- often as you like.
-
- When you have read all the help you want, you can return to where
- you left the programme by pressing <Esc>.
-
-
- Data Entry
- ----------
-
- The Data Entry screen allows you to specify the temperature and
- pressure at which the physical properties will be calculated. This
- can be done in several ways, described below.
-
- Apart from specifying these conditions there are other options
- available on the Data Entry screen. Pressing <F3> will display the
- physical properties that do not vary with temperature or pressure.
- Pressing <F4> allows you to specify the units in which your entry is
- made, and in which the properties will be displayed. If you have a
- colour video card <Alt C> and <Alt M> will switch between colour and
- monochrome. If you want to exit WASP press <Alt X>.
-
- If you want to calculate the physical properties under SATURATED
- solid/vapour or liquid/vapour conditions you need to specify either
- the temperature or pressure, but not both. The entry must be made
- on the top line and the <TAB> key is used to select which of these
- you will enter. For example, if the programme is requesting you to
- enter the temperature on the top line of the input box, but you want
- to specify the pressure, press <TAB> to swop the two lines.
-
- Under saturated conditions it is not necessary to press <ENTER>
- after you have keyed in the number. Just press the <SPACE BAR> and
- the corresponding value will be inserted and the properties will be
- calculated.
-
- In order to calculate the physical properties at conditions other
- than saturated, you have to specify both the temperature and the
- pressure. You can swop the two entry lines with <TAB>, and you can
- move the cursor from one line to the other with the up and down
- arrow keys. When you have keyed in the value on the bottom line
- pressing <ENTER> will calculate the physical properties.
-
-
- Water and Steam Properties - Version 1.01 Page 5
-
-
-
- As you enter the conditions the programme will check that they fall
- in the range covered by the data. If they are not valid entries,
- the allowable range will be displayed at the bottom of the screen in
- the units selected, and you will be asked to re-enter the value.
- The allowable temperature range is from 166 to 1273 Kelvin (-160 to
- 1832 Fahrenheit) and the allowable pressure range is from 3.4e-7 to
- 100 000 kPa absolute (4.9e-8 to 14500 PSI absolute).
-
- During data entry the left and right arrow keys, and the <HOME> and
- <END> keys, allow you to move the cursor back and forth within the
- entry field. The <DELETE> key deletes the character under the
- cursor and the <BACKSPACE> key deletes the character to the left of
- the cursor. <Ctrl BACKSPACE> will delete the entire entry field.
-
- If the entry field already contains a number and you press a numeric
- key before any of the editing keys, the programme will assume that
- you want to override the original entry and will delete it before
- displaying the character you have keyed. If you want to accept what
- is already displayed just press <ENTER> or <SPACE BAR>, depending on
- whether you are working under saturated conditions or not.
-
- Data entry always works in INSERT mode, i.e. characters under and to
- the right of the cursor will be moved to make space for the new
- character.
-
- Only numeric characters will be accepted, except that <e> can be
- used to signify exponential notation. E.g. the value 2000 can be
- entered as 2e3, and 0.001 can be entered as 1e-3.
-
-
- Result Screens
- --------------
-
- There are several different formats for the result screens that
- display the physical properties. The format of these screens varies
- according to the phases that are present, and according to the
- choices that you have made. However, all screens follow the same
- basic pattern.
-
- The highlighted box at the top of the screen shows the temperature
- and pressure that you specified and also shows the phases that will
- be present.
-
- The main result box in the centre of the screen gives all the
- physical properties, the units and the values for each phase. Every
- alternate line in this box is highlighted to make it easier to
- follow the line across the screen.
-
- The bottom line of the result box shows some of the options
- available. If you press <Esc>, or in fact any alphanumeric key, you
- will be returned to the Data Entry screen.
-
- The <F2> function key toggles between the full and brief versions of
- the output screens. The brief results screen gives the properties
- usually found in "Steam Tables". The full screen gives the same
-
-
- Water and Steam Properties - Version 1.01 Page 6
-
-
-
- information plus the less frequently needed properties. The brief
- screen is easier to use because it contains less information.
-
- When you exit from WASP the programme will make a note of which
- result screen you had chosen, and will use this choice when it is
- re-started.
-
- Although it is not shown in the list of options you can use the <F3>
- function key to display the fixed physical properties. The <F4> key
- allows you to choose the units in which the properties are
- displayed. You can select standard sets of units, or choose the
- units for each property individually. Further information on making
- these choices is available in the section on Selecting Units below.
-
- If you have a colour video card pressing <Alt C> and <Alt M> will
- switch between colour and monochrome output. You can exit from WASP
- by pressing <Alt X>.
-
-
- Fixed Properties
- ----------------
-
- The physical properties of water that do not vary with temperature
- or pressure can be displayed by pressing <F3> at the Data Entry
- Screen or at the Result Screen displaying the variable properties.
-
- The main result box in the centre of the screen gives all the
- physical properties, the units used and the values for each physical
- property. Every alternate line in this box is highlighted to make
- it easier to follow the line across the screen.
-
- The bottom line of the result box shows some of the options
- available. If you press <Esc> or <F3> you will be returned to the
- screen from where you requested the fixed properties.
-
- The <F4> key allows you to choose the units in which the properties
- are displayed. You can select standard sets of units, or choose the
- units for each property individually. Further Help on making these
- choices is available in the section on Selecting Units below.
-
- If you have a colour video card pressing <Alt C> and <Alt M> will
- switch between colour and monochrome output. You can exit from WASP
- by pressing <Alt X>.
-
-
- Selecting Units
- ---------------
-
- The units that are used for data entry and for displaying the
- physical properties can be chosen in sets, or individually for each
- property. The first 5 options on the menu select the sets of units
- and the balance of the options are for the individual units.
-
- There are two ways to make a selection from the menu. The first is
- the "Point-and-Shoot" method. Use the arrow keys to highlight your
-
-
- Water and Steam Properties - Version 1.01 Page 7
-
-
-
- choice, and then press <ENTER>. The second method is faster,
- requiring only a single key press. Simply press the alphabetic key
- corresponding to your choice.
-
- You can see which units are currently selected by pressing
- <SPACE BAR> while the menu is displayed.
-
- If you select one of the sets of units, the programme will display
- the units that will be used for each property. Press <Esc> to get
- back to the menu, and again to get back to the point from where you
- called the Units menu.
-
- When you choose to change the units for an individual property you
- will be shown a sub-menu with the available units. In the sub-menu
- the currently selected unit will be highlighted. The method for
- selecting the option from the sub-menu is exactly the same as for
- the main menu. After you make your selection the programme will
- automatically return to the main menu, from where you can choose to
- change the units for another property, or you can press <Esc> to
- quit the menu.
-
- The only individual unit that needs further explanation is option
- "H", ie Density / Specific Volume. Strictly speaking density and
- specific volume are not the same property, but in WASP they are
- dealt with together as the one is just the reciprocal of the other.
-
- Whenever you exit from WASP, the programme will check to see if the
- selected units have changed. If they have, it will give you the
- option of saving the new selection of units for use in the next
- session. You can revert to the last saved selection of units at any
- stage during a session by selecting the first option on the units
- menu.
-
-
- Using the Menus
- ---------------
-
- All the menus in WASP follow exactly the same format. There are
- three ways to make a selection from a menu.
-
- The first is the "Point-and-Shoot" method. Use the arrow keys to
- highlight your choice, and then press <ENTER>. The second method is
- basically the same as the first, except that the mouse is used to
- highlight the choice. The left mouse button functions as an <ENTER>
- key and the right button as an <Esc> key.
-
- The third method is the fastest, requiring only a single key press.
- Simply press the alphanumeric key corresponding to your choice.
-
-
- Exiting from WASP
- -----------------
-
- When you want to exit from WASP press <Alt X>. As the programme
- quits it will check to see if the selection of units to be used has
-
-
- Water and Steam Properties - Version 1.01 Page 8
-
-
-
- been changed from what it was at the start of the session. If the
- selection was changed, the programme will request you to confirm
- whether you want it to start up the next session with the new units,
- or with the same selection as the current session did.
-
- The programme will also save your current selection of full or brief
- result screen output, and whether you were using the colour or
- monochrome display. These selections are saved automatically and
- you will not be prompted to confirm that you want them saved.
-
-
- Accuracy Considerations
- =======================
-
- The accuracies listed below are given in good faith and reflect our
- testing of the WASP correlations against a wide range of sources.
- We believe that the accuracies attained are well within the bounds
- normally required for process engineering design work, but if you
- are doing very exacting calculations (particularly if they are near
- the critical point) you should cross check your data.
-
- This cross checking of data is good engineering practice for
- important design work and its necessity was brought home to us in no
- uncertain way during the testing of WASP. We found several
- typographical errors in well known data sources and some of the data
- tables were just plain wrong. There are probably quite a few
- installations around the world that were designed using this data !
-
- There are accuracy advantages in using a package like WASP in that
- you will avoid the typo's in the published tables, you will get
- better interpolations between the published data points and you will
- not be exposed to the risk of arithmetical errors in converting to
- different units.
-
- The "worst" errors are the worst that we found, and in general were
- near the critical point.

- The Shareware Distribution System
- =================================
-
- Although shareware is often thought of as a type of software, it is
- actually a form of software distribution. This section gives
- details on the shareware system and how it works.
-
- The Shareware distribution system can be seen as having developed
- naturally in the environment of free enterprise and innovation that
- characterised the PC industry in the early 1980's. It has continued
- to grow and today there is a huge variety of high quality software
- available at reasonable prices. Shareware in fact covers a wider
- range of subjects than commercial software. Some of the areas that
- are particularly well represented are databases, word processors,
- spreadsheets, CAD, games, DOS utilities, menuing systems, education,
- accounting and programming support.
-
- A support industry that includes magazines, disk distributors and
- bulletin board systems has grown up around the Shareware system.
-
- If you are new to Shareware you may like to have a look at some of
- the software available from the disk distributors. They supply
- evaluation copies of Shareware packages for about US$10.00 per disk.
- This payment is for copying the software and the price of the disk,
- and NOT for the software itself. If you like the software you send
- your payment to the author and not to the distributor.
-
- Some distributors with good catalogues are :-
-
- 1 Public Brand Software, Box 51315, Indianapolis,
- IN 46241, United States of America.
- 2 The Public Domain and Shareware Library,
- Winscombe House, Beacon Rd, Crowborough,
- Sussex, TN6 1UL, England.
- 3 JSE, 73 Highway, Fish Hoek, 7975, South Africa.
-
- The basic concept of Shareware is that the author retains the
- copyright and all other commercial rights to the software and
- documentation, while allowing, and indeed encouraging, wide copying
- and distribution of the package.
-
-
- Water and Steam Properties - Version 1.01 Page 11
-
-
-
- There are a few restrictions that authors place on distribution.
- All copies must be full copies of the entire package with no
- modifications or additions. Copies may not be sold for more than
- the cost of the disk, the labour of copying and a reasonable profit.
- When selling copies the distributor must state that the software is
- free for evaluation purposes only and payment must be made to the
- author if continued use is made of the programme.
-
- Effectively the Shareware author is relying on the users of his
- software to do his marketing. For this reason Shareware is often
- also called User Supported Software. This system eliminates almost
- all the advertising and marketing costs that make up the major
- portion of the operating budgets of commercial software
- distributors.
-
- There are many advantages in Shareware to users and authors. The
- cost to the user is low because no money is wasted on advertising
- and fancy packaging that add no real value to the software. The
- biggest advantage to the user is that it is a true
- "try-before-you-buy" system. The software can be fully evaluated on
- the user's hardware and in his own environment before payment is
- made.
-
- Another advantage to the user is that by its very nature Shareware
- cannot be copy protected. This eliminates the hassle of key disks,
- dongles, immovable sectors on hard disks, special install and
- uninstall routines and all the other wonderful schemes that have
- been devised to try the user's patience.
-
- As there is no middleman (middlemen ?) not only is the cost kept
- lower, but the user is also closer to the author and is able to
- write directly to him for help and advice. Shareware authors
- generally encourage users to send in "wish-lists" of desired
- features, and are quite responsive to those requests.
-
- There are of course also advantages to the authors who use Shareware
- to distribute their products. The cost of launching a new product
- via Shareware is much less than via normal commercial channels.
- This has allowed smaller software houses to market innovative and
- highly specialised software that would otherwise simply not be
- profitable. Running costs are also lower as there are almost no
- marketing or advertising costs.
-
- The software industry is currently going through a consolidation
- phase with the big-boys buying each other, and some of the smaller
- boys, out. But a significant number of the small companies have
- switched to Shareware and have made some really top class software
- available via this route.
-
-
- WASP Licensing Policy
- =====================
-
- This section describes the WASP licensing policy. The WASP licence
- agreement is basically the usual Shareware policy. Recipients of
-
-
- Water and Steam Properties - Version 1.01 Page 12
-
-
-
- copies of the WASP package are requested to use the system for a few
- weeks to determine its value. You only need to pay for it if you
- believe that it offers the value of the asking price. If it does
- not meet your needs or standards then it costs you nothing. WASP
- can be bought either as a single-user system for US$ 40.00 or as a
- multi-user site licence for US$ 75.00 (or the equivalents in SA
- Rands).
-
- The single-user licence entitles you to install the package onto
- several different computers on a single site, provided that it is
- not run on more than one machine at a time. If it is likely that it
- will be run simultaneously on two or more machines we request that
- you purchase a site licence.
-
- You can register your copy of WASP by either filling in the
- registration form in the file REGISTER.DOC or by pressing <Alt R> at
- the Shareware Distribution screen and answering the questions. This
- will print the completed form on your printer. If you use the
- REGISTER.DOC file you can print it out and fill it in manually, or
- load it into your word processor for completion. A copy of
- REGISTER.DOC is attached to the end of this manual.
-
- In return for your registration fee we will send you a copy of the
- latest version of WASP with your company's name listed as the
- licence holder on the title screen.
-
- We do not send printed copies of the manual to purchasers of WASP.
- Instead there will be a file containing the manual on the disk for
- you to print out (just like this manual). This is done for three
- reasons. Firstly it keeps the price down, secondly it allows
- revisions and improvements to be included immediately rather than
- having to run down stocks of old manuals, and thirdly we believe
- that well-written software should not need a manual ! What is your
- attitude to manuals ? Do you read them ? Please let us know if you
- feel a printed copy is important.
-
- What else do you get for being honest and sending in your
- registration fee ? Well, we can't promise to fill your mail box
- with junk mail, but if you don't register we have no way of telling
- you of updates and of our other software products.
-
- Registered users are also entitled to support by mail. If you have
- any problems please write and we will do our best to help. We would
- also like to hear of any features you would like to see added to
- WASP. Are there units that you use that we have not built in ?
- Let us know and if they are anything more reasonable than
- bathtubs/fortnight we will build them in. Are there standard
- calculations that you would like built in ? If so please send
- details and samples.
-
- Whether you register or not, may we request that you give away
- copies of WASP to your friends, colleagues, customers, suppliers,
- students and anyone else who would have a use for it. We would also
- appreciate it if copies are uploaded to BBSs.
-
-
-
- Water and Steam Properties - Version 1.01 Page 13
-
-
-
- The only restriction on distribution is that we ask that you always
- give away copies of the full system with all its files, and that
- they are not modified in any way. The full list of files is given
- in the section on Installation and Startup at the beginning of this
- manual.
-
- Suppliers of hardware and software may bundle WASP with any of their
- other products, subject to the above restriction, and that it is
- clearly stated that any payment made is solely for the other product
- and not for WASP.
-
-
- Registration to Engineering Schools
- -----------------------------------
-
- Any University or Technical College involved in the tertiary
- education of engineers can obtain a licence for WASP free of charge.
- In order to get your registered copy of the latest version please
- fill in the registration questionnaire in the normal way and get
- your Head of Department to write a covering letter on your School's
- official letterhead, but send NO MONEY.
-
- All that we ask in return is that you make the registered copy
- available to all students and staff so that we do not get duplicate
- requests, and hopefully the students will take their copies with
- them when they go out into industry.
-
-
- Bug Reports and Wish Lists
- ==========================
-
- We have put many hours into the checking of this programme and were
- not aware of any bugs at the time of release. However, we are also
- aware that the most subtle bugs are unearthed after release. We are
- therefore most grateful to those who report bugs to us. Please give
- as much detail as possible on the bug so that we can re-create the
- circumstances on our equipment. Please include details of your
- hardware, operating system, resident programmes and so on.
-
- Our experience gained over many years and with the development of
- several packages has shown us that no matter how much effort we put
- into designing and planning we can never hope to match the combined
- creativity of our users. We would like to hear of any features you
- would like to see changed or added to WASP. Are there units that
- you use that we have not built in ? Let us know and if they are
- anything more reasonable than bathtubs/fortnight we will build them
- in. Are there standard calculations that you would like built in ?
- If so please send details and samples. Would you like to be able to
- use WASP on operating systems other than DOS ? Are there any
- operations in WASP that are awkward and not intuitive or standard ?
- Let us know how you would prefer it to be. (We know of a word
- processor package that refused to put the Help key on <F1> until
- they got to version 6 ! Hopefully we can be more responsive than
- that.)

- Other Engineering Packages from Katmar Software
- ===============================================
-
- Our aim at Katmar Software is to provide top quality process
- engineering utility software at realistic prices. WASP is the first
- of our packages to be released. Other applications that we have in
- various stages of development between conceptual design and beta
- testing are more physical property database and estimation packages;
- flow calculations in pipes, valves and orifices; process equipment
- design and evaluation programmes and so on.
-
- As soon as these packages are released as shareware we will advise
- all registered users of WASP. If there are particular application
- areas where you have a need for low cost utilities please let us
- know as we would like to focus our limited resources where they will
- be most effective.

- WASP Registration Form
- ----------------------
-
- The following registration form is provided for those who would like
- to fill in their order form manually. You can also complete the
- registration form by loading the file REGISTER.DOC into your word
- processor and filling in the missing information before printing it
- out. Probably the easiest way to register is to run the WASP
- programme and press <Alt R> at the Shareware Distribution Screen.
- The programme will ask you the questions and you can type your
- information directly into the programme. It will then print out the
- registration form on your printer.
