-
- What is Currency Convert you may ask?
-
- Well, hopefully the name gives a little bit away as to its origin. It
- is an exchange rate conversion program born out of frustration, due to my
- never having seen any other similar program in the Public Domain for the
- AMIGA.
-
- In its simplest form it will Convert a given Currency over
- to one of three Countries formats. Namely:-
-
-
- Sterling to Australian
- Australian to Sterling
- U.S. to Australian
- Australian to U.S.
- Sterling to U.S.
- U.S. to Sterling
-
-
- I often read overseas AMIGA magazines to compare Software/Hardware
- prices with those here in Australia and have often wished there was a
- quicker way than using the calculator to work out the exchange rate between
- Australia and U.S.A. or Australia and England etc.... Plus I can never
- remember the exchange rate any way, and often end up ringing the bank or
- grabbing the daily NewsPaper to look up the exchange rate for the day.
-
- Currency Convert I hope will solve part of that problem.
-
- Supposing you see in a U.S. magazine a software program costing
- around $ 400.50, it would be nice to know how much in Australian Dollars
- that would be so that a comparison could be made with Australian prices.
- Whilst it is always best to buy from your home Countries dealer, if you work
- on a tight monetary budget, it is on occasions, sometimes a little cheaper
- to buy from overseas.
-
- Hence, here now enters Currency Convert.
-
- This program will take input from the user, of say $ 200.50 plus
- if you know it, the exchange rate between the Countries concerned
- ( converting U.S. $ to Australian $ ). Enter Exchange rate of $ 78.40,
- then the converted amount of Australian $ 255.74 will be output.
-
- When designing the layout of the program I went to great lengths to
- ensure that it was V E R Y user friendly. I have attempted to catch every
- ERROR that could possibly be input so that the outputted money figure will
- always be as accurate as possible ( of course dependent on accurate exchange
- rate input from the user ). The program can be started from the both the
- CLI and WORKBENCH and will sense from which mode it is provoked and thus
- the startup procedures will vary slightly, as will be explained below.
-
-
-
-
-
- CLI STARTUP
-
- At the CLI prompt type program name ( from here on called Convert as
- it appears in its release form ) with no additional arguments. After
- selecting <RETURN>, the screen display will consist of a HELP menu explaining
- its operation which is fairly self explanatory. The allowable arguments for
- provoking the exchange rate conversions are:-
-
-
- Sterling to Australian, type > Convert [ea] [-r]
- Australian to Sterling, type > Convert [ae] [-r]
- U.S. to Australian, type > Convert [ua] [-r]
- Australian to U.S., type > Convert [au] [-r]
- Sterling to U.S., type > Convert [eu] [-r]
- U.S. to Sterling, type > Convert [ue] [-r]
-
-
- There is a second argument that can be used if you wish, following
- the country of origin option and that is [-r].
- What this does will leave you in the [Re-enter Mode] so that after
- each conversion is completed, instead of the CLI prompt returning, you will
- be prompted for a new conversion option ie: [ue]. This loop will
- continue until you have enjoyed dreaming of cheaper prices and decide to
- QUIT the program - this can be done at A N Y P R O M P T that appears in
- Convert by simply typing the letter "Q" and selecting <RETURN>.
-
- There are a number of additional options available to the user once
- the first prompt appears....
-
-
-
- USAGE: Converts Australian $ to U.S. $
-
- Enter amount in Australian Dollars $ 200.50 - 1st prompt
-
- Enter U.S./Australian exchange rate in cents ¢ 78.40 - 2nd prompt
-
-
- Converted to Australian Dollars = $ 255.74 ¢ - amount to pay
-
-
-
-
-
-
- FIRST PROMPT
-
- Entering "?" will display a the currently known exchange rate as of
- the date when this program was completed "06/11/91"
- This action can also occur at the second prompt.
-
- Type in "m" and this will abort the current conversion status and
- return you to a menu of options and selector prompt.
- This action can also occur at the second prompt.
-
- Entering "h" will display an extensive display of all the arguments
- available to the user from within the program as explained above.
- This action can also occur at the second prompt.
-
- In addition there is full ERROR CHECKING. Try a few errors of say
- alphabetical input, number input lower than 5, control codes or whatever and
- unless there is something I have missed, you should get back an error report!!
-
-
-
-
-
- SECOND PROMPT
-
- Entering "b" will abort the prompt and return you to the first prompt.
- This function is useful in case you realize that the input at the 1st prompt
- is incorrect and you wish to change it.
-
- Enter in "d" and this will type out a default exchange rate I have
- encoded in that was current as of "06/11/91". This is an active function
- and will actually complete the calculation resulting in an answer displayed.
- This function is only meant as an example but is useful if you are only after
- an idea of an approximate exchange rate value.
-
-
-
-
-
-
- WORKBENCH STARTUP
-
- If beginning Convert from the workbench icon(.info), naturally the
- startup arguments cannot be switched in at program execution, so I have allowed
- optional input to be selected after Convert is run.
- Clicking on the program icon will result in an output window opening up
- of 604 X 200 (ntsc size) in which will appear the following display....
-
-
-
- O P T I O N S M E N U
-
- Sterling to Australian, type "ea"
- Australian to Sterling, type "ae"
- U.S. to Australian, type "ua"
- Australian to U.S., type "au"
- Sterling to U.S., type "eu"
- U.S. to Sterling, type "ue"
-
-
-
- Enter your selection :
-
-
-
- After entering selection and <RETURN> the program will operate
- fairly much the same as when in the CLI mode with one exception. If you enter
- at the prompt "h" you will find a fairly extensive HELP display that is
- along similar lines to that displayed if run from the CLI with no arguments.
- This feature was added to allow new WORKBENCH users to gain additional HELP
- if unsure of some of the programs features. This display like all others is
- based on a timing feature and will display for a preset amount of time and
- then return to a prompt etc - if you find it is not long enough then hit the
- space bar once, and when finished reading, hit <RETURN> and the program will
- continue.....
-
-
- Remember, at any prompt regardless from where "CONVERT" was begun,
- typing in the letter "Q" will abort the program.
- All input incidently is NOT CASE SENSITIVE.
-
- The selection of Countries that I used for this version of "CONVERT"
- was based on the where I currently peruse pricing of Software/Hardware. I am
- quite happy to encode other exchange rates into the program only if I am
- provided with full details including the exchange rate between the nominated
- countries.
-
- Any compliments "good or bad" about "CONVERT" would be
- appreciated, so I would love to hear from you at the address indicated below.
-
-
- Hope you find a use for "CONVERT" and that it becomes a useful addition
- to your program requirements!!
