THE FOREX FORM
==============
This form will appear whenever more than one currency is used in
a transaction. This will occur when a currency is entered in the
currency box next to the 'from' account or when the currency of
the 'to' account is different from the 'from' currency. It is possible
to have 2 accounts with different currencies conducting a transaction
in a third currency. All transactions involving more than one currency
remain fully editable.
RESULTS. The 'forex' facility will convert a transaction amount into
the equivalent amount in the native currency(s) of the 'from' and 'to'
accounts. These results are shown in the 2 'results' boxes.
TRANSACTIONS RECORDS. Whenever a transaction uses more than one
currency !Pennies will always convert the amount of the transaction
into the account's native currency for display and use within the
account. The transaction record will also contain details of the
amount and currency of the transaction in the 'to' currency and the
currency of the transaction.
AMOUNT. The amount in the currency of the transaction should be
entered in the normal way into the 'amount' box in the TRANSACTION
window. This amount will be automatically entered into the FOREX
window when either:
RETURN is pressed with the cursor in the 'amount' box
SELECT or ADJUST is clicked over the 'comments' box
RESULTS is clicked in the 'forex' window
The transaction is ENTERed-in this case the calculations will
be made and the FOREX window will show the results
briefly before closing. If all the rates are already known
they will be used-if a rate is missing then a level rate of 1
to 1 will be used.
The amount cannot be entered directly into the FOREX amount box.
RATES. The prime piece of data necessary to calculate the amounts in
other currencies is an exchange rate. The FOREX window allows entry of
these rates in a variety of ways.
1.If a transaction involving the 2 currencies has been made before
then the rate will be stored (on disc) so a rate will already be
known and will be automatically entered into the appropriate rate
boxes (next to text "X per Y" under the 'from account' and 'to
account' headings). If no rate is known then a warning will be given
and a level rate of 1 to 1 will be used as a default rate.
2.Rates can be manually entered into the rate boxes and edited at
any time the window is open (note what the rate is in X per Y before
entering-it is easy to enter it the wrong way round!)
3.The known results of a transaction can be entered into the results
boxes and the rates calculated from the amount by clicking on the
RATES button.
CALCULATION.Whenever the ENTER button in the TRANSACTION window is
clicked then the forex procedure will check the data, calculate the
results, display them briefly in the FOREX window and then close the
window. The results can also be seen after the amount has been entered
into the TRANSACTION window 'amount' box as above. If you wish to
check the results after editing any rate or amount just click over the
RESULTS button.
ROUNDING ERRORS.When the results are calculated from a rate the result
is rounded to a whole number of pence or equivalent. You may notice
that as the result is calculated the rate values change slightly (eg
from 1.5 to 1.4999999). This is because !Pennies first calculates the
result using the rate entered then recalculates the rate from this
result and displays it to show you the rate that gives the exact
answer. This system avoids problems if/when the entry is edited.
EDITING. Whenever a transaction is edited that involves more than one
currency the FOREX window will open allowing you to edit the data.
Commonly the rate you have entered initially will not be the
one the bank uses so the amount appearing on your bank statement will
differ from the one here. In this case just enter the correct result
into the appropriate results box and click on the RATES button to
adjust the rate to the correct one. Note that if the 'from' and 'to'
currencies are the same then the correct result only needs to be
entered in the 'from' result box-it will be automatically entered into
the other when either calculation button is clicked.
