VMS Help RTL Routines, MTH$, MTH$HCOSD, Arguments  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 h-cosine

    OpenVMS usage:floating_point
    type:         H_floating
    access:       write only
    mechanism:    by reference

    Cosine of the angle specified by angle-in-degrees. The h-cosine
    argument is the address of an H-floating number that is this
    cosine. MTH$HCOSD writes this cosine into h-cosine.

 angle-in-degrees

    OpenVMS usage:floating_point
    type:         H_floating
    access:       read only
    mechanism:    by reference

    Angle (in degrees). The angle-in-degrees argument is the address
    of a floating-point number. For MTH$HCOSD, angle-in-degrees
    specifies an H-floating number.
