subroutine interp2d

[fortran88]

Hello all

According to interp2d.f,
the outputs are shp(3,16,l) and jac(l).

How it can be possible?
Because the list of variables in the subroutine definition statement is like
interp2d(l, xl,ix, ndm,nel, flag). There is shp and jac
As far as I know, the variables in the list can be used to transfer information from the subroutine and into the subroutine.

thanks for reading this
