C --DOFNC2 performs an intrinsic or external function with two parameters

C --on each array value.

|
|
C --Parameters:
|
|
C -- FUNC - IN - the intrinsic or external function
|
|
C -- PARTYP - IN - the parameter type (element must be handled differently)
|
|
C -- LENARY - IN - the length of the parameter arrays
|
|
C -- NELBLK - IN - the number of element blocks
|
|
C -- IXELB - IN - the cumulative element counts for each element block
|
|
C -- ISEVOK - IN - the element variable truth table for each element block
|
|
C -- NUMIX - IN - the number of selected values; <0 if all
|
|
C -- IXNODE - IN - the indices of the selected nodes (only if NUMIX>=0)
|
|
C -- IXELEM - IN - the indices of the selected elements (only if NUMIX>=0)
|
|
C -- PARM1 - IN - parameter 1 array
|
|
C -- PARM2 - IN - parameter 2 array
|
|
C -- RESULT - OUT - the returned result array
