CONVERT

Convert 2.00 ============ Convert is a tool for the Psion Series 3a to make all kind of conversions. You can use its predefined conversion tables, you can extend them easily, and you can even write your own conversion tables. INSTALLATION ============ To install Convert, copy the file Convert.app to any \App directory. If you want to use the predefined conversion tables, copy the *.cnv files into a \Cnv directory on any drive. Then install the application as usual using the "application / install" menu command. USAGE ===== Convert uses a special table view to handle its conversion tasks. Each line takes the following data items: Unit name - is used as an identifier or label for an unit. Unit abbreviation - is a unique abbreviation for the related unit. Formula - is the conversion function, written in the form: <unit1>=<unit2><operator><operand> There are two different types of data items: Base unit - the first table element to be entered is called the base unit, which means that it can not refer to any existing unit. Unit - each one of the other items can refer to any other units by means of formulas. Using existing conversion tables -------------------------------- To use an existing conversion table select any entry by using the cursor keys, simply enter a number followed by an ENTER. After calculating the conversions the result of the calculation will update the other table entries. That's it! Defining a new conversion table ------------------------------- Start a new file from the system menu or by selecting the "New File" menu command. Press SHIFT ENTER to launch the Base unit dialog. Provide a name for the new base unit and a (meaningfull) abbreviation. For example: Unit name: Metre Unit abbreviation: m After updating, you can enter any number of additional entries, providing a name and a related formula, for example: Unit name: Centimetre Formula: cm=m*100 IMPORTANT - the formula reflects the numbers relation, not the units one. So if you have a value of 3 metres, you will come to the value of the centimetres by multiplying 3 by 100 = 300 cm! Please note the context sensitive help mechanism! Keyboard usage -------------- Move the record selection by using the cursor up/down/page up/page down and Home/End keys. Shift the display to the left/right by using the cursor left/right keys. Remove an entry by pressing the Delete key. File/New file ------------- Create a new file. File/Open file -------------- Open an existing (*.cnv) file. File/Compress ------------- Compress the current database after record changes or deletions to save space on the disk. Entry/New entry --------------- Enter the data of a record.
