G.1.4 Routines with Prototype or Syntax Changes

The following routines have changes to their argument syntax with the new DECthreads implementation:

The following routines no longer support previous nonstandard DECthreads datatypes that were documented in the previous release. If your original code used the standard (real) datatypes, then this list may not impact your code.
