Edit properties

Editing properties is done via the 'editprop ' -command or via hotkey 'g'. If you execute this command, the property editing box will pop up. In picture 7.1 , you can see the property editor when editing a sin voltage source.

  The 'Quit'-Button closes the box if you have finished editing. The properties will be updated internally if you pess 'RETURN' , 'TAB' or 'ESC'.
'RETURN' will advance the input focus by one line, 'TAB' will revert it.

DON'T FORGET TO FINISH EACH INPUT WITH <RETURN> or <TAB> or <ESC>.
OTHERWISE, YOUR INPUT WILL NOT BE STORED.
TRY IT OUT: MAKE AN EDIT WITHOUT PRESSING 'RETURN', CLOSE THE PARAMETER BOX AND REOPEN IT.

  Pushing the 'Save variables to file varlist'-Button will save the contents of the property box into a file called 'varlist'. These properties can be read later by another design (schematic).

The property editing box will have two buttons 'Display following entries' and 'Display previous entries'     if the number of properties exceeds 10. This is the case when you edit parameter boxes or the options- box which defines SPICE3-'.OPTIONS' .

   

The properties are internally stored as a string. There is no syntax checking at all. Inputs like '12.0erte-12' instead of '12.0e-12' are stored like any other input and will be netlisted as 0.0 later because the string-to-real function will fail.

     

Property strings have a length of 40 characters. So, if you want to use variables and expressions, be sure that the variable names and expressions are not too long. But don't worry, you will get an error message if the variable lengths are too long.
