All custom functions must be given a unique name, if they are to be used in your work with Fireworkz. The name is expressed as the first parameter to FUNCTION
. Certain rules apply to the names you can give your custom functions:
The maximum length permitted is 24 characters.
Names can include letters, numerals and the underscore character.
You may only use digits after an underscore character has been used. This is so that Fireworkz can distinguish between custom function names and cell references. So my_function1 and function_1 are valid custom function names, but function1 is not.
The name should appear in the following way:
FUNCTION("my_function")
