For developer use. This command is used inside a function that is called by the nodefunction() command. It returns the parameter passed to nodefunction specified by index as a number. The first additional parameter passed to nodefunction() is parameter 1, the second is parameter 2, etc. Parameters can also be retrieved using parnode() and parstr() for casting them as a treenode and string respectively. * K/ k% c% X% V$ Q$ C
Example: double passedval = parval(3);6 x5 _( {/ b+ ]$ V2 c( m
" Q8 p2 |% g3 j: J
This sets passedval equal to the number that was passed to nodefunction() as parameter 3. |
