            Some annotations to the IDL version
            ===================================

This IDL version has been written by K.H.Muehlhaeuser and is based on the
original Fortran 77 sources written by Mike Hapgood.

What has been changed in the IDL version:

o  If the environment variable CLUSTRAN_DIR used to locate the data file
TERMS2.DAT is not defined, the procedure terms_init.pro is used instead.
(Attention: If TERMS2.DAT will be updated at any time, terms_init.pro
must be updated, too)

o The main interface TRANSYS can be called either by
	TRANSYS, x, sys, form, rcode, outsys, outform  (as in the F77 version)
or by
	TRANSYS, DS, outsys, outform                   
where the structure DS is defined by
	DS = {ds_struct, vect:[0.d,0.d,0.d], sys:'', form:'', rcode:0}

o All float variables (F77 version) are now defined as double precision.
