11. Appendix C: Deprecated and Obsolete Subroutines

The following twelve subroutines are listed only for reference. They should not be used in new programs.

The PARMS files created by x\zvpopen, x\zvpout, and x\zvpclose should be avoided if possible. PARMS files are used to communicate parameters between programs (the receiver has a PARMS parameter to receive the file). They work and are portable, but the internal implementation is necessarily non-standard. Other communication methods, such as TCL variables or IBIS interface files, are recommended instead.
