Variables, Objects, Functions and Methods : PML Functions and Methods : Storing and Loading PML Functions
When a PML Function is called it is loaded automatically from its source file in a directory located via the environment variable PMLLIB. The name of the external file must be lowercase and must have the .pmlfnc suffix. The source of a PML Function invoked as !!AREA or !!Area or !!area all correspond to the file named area.pmlfnc.
|
Note:
|
The!! signifies that the function is user-defined and that it is global - but !! does not form part of the external filename. All user-defined functions are global and only one may be defined per file.
|
|
Note:
|
The define function must be the first line in the file and that its name and the file name must correspond.
