    The /SEXAGESIMAL option allows to use sexagesimal expressions in assign-
    ments. This option is only valid for scalar variables. Units of the  op-
    erands can be provided by optional characters chosen in D)egrees, H)ours
    or R)adian. The first unit is for the output, the second for the  input.
    Radian  is  an  invalid unit for the sexagesimal string. Degrees are as-
    sumed by default for both operands.

    The first form converts the sexagesimal expression into a numerical val-
    ue stored in the assigned variable. Mathematical expressions can be used
    for each elements, provided they are separated by a semicolon.

    The second form converts a numerical value into the sexagesimal notation
    stored in the assigned character variable.
