Similar Bugs in CHAIN_2D

The legacy package CHAIN_2D shares uses some of the same subroutines as SWMS_2D, so it contains similar bugs. The loss of precision in subroutine RESET and in the calculation of 1/tanh(x) - 1/x in subroutine WEFACT affects CHAIN_2D, as well. For Example.2, compare the last line of the console output...

I appreciate the prompt response. I have sent you email with the URL to a shared folder in the cloud that contains the corrected source files for SWMS_2D and SWMS_3D. The polynomial approximation to the expression 1/tanh(x) - 1/x was obtained using the Taylor expansion at x = 0: Using Maple mathemat...

These old packages, I realize, are no longer maintained and may see little use these day...
