MANUAL CALCULATION
~~~~~~~~~~~~~~~~~~~~
To start manual calculation: after changing any options if required,
highlight item 3 in the main menu and press return. Manual calculation is the
normal mode of operation for Thermo Calc. It accepts any valid input entered
via the keyboard and immediately displays the result.
Firstly it displays a header showing the current settings of all the
options and then prompts you for an input. If the input is valid (see section
headed Valid Keyboard Inputs) it then displays both the input and the result
in two columns. (The reason it redisplays the input is that it does so in a
consistent, readable format, acting as a visual check on the input and
tidying up the printout if enabled). If the printer option has been enabled
then the header and both columns are also printed. If the input is invalid
then a warning message is displayed (and printed). If the input is only just
outside the valid range then a result is given along with a message to the
effect that the result is only approximate.
When you have finished, or to change any of the options, press RETURN with
no input. This returns you to the main menu. BUT REMEMBER, any results not
printed will be lost. Also, any results which scroll off the top of the
screen will be lost, so it is advisable to enable the printer if more than a
screen full of results are expected. The contents of the screen can, of
course, be printed at any time by pressing the Prt Sc key.
