I wish to thank all of you who took the time to let me know about the several software and documentation errors. Without your help TSXLIB could very well degenerate into something of a pitiful mess. Please keep up the very fine debugging and proof reading. The FORTRAN sources for some test programs have been added to the distribution kit. These programs have all been used with both F66 and F77. I am unable to test many of the TSXLIB routines on my system and would appreciate any help any of you users can offer in testing and furnishing me with the FORTRAN sources for your test programs. A number of incompatibilities with F77 function called routines have been removed. With the major change in the privilege structure of TSX V6.0, many of the older routines were affected. Hence, many changes have been made to both the code and the document. One of you suggested that I standardize the error return information in TSXLIB to be zero for no error or no exception. This would be great, but not very convenient to implement. However, as TSX evolves, so will TSXLIB. A negative (-1) return is becomming more common as the no error or no exception condition.
