Commands, variables, SIC logicals and symbols

There has been an important effort to clarify the names of the various GTV objects, to fix or improve their behavior, and to clean out the obsolete ones. This can imply here and there an action from the user to make its procedures compatible with the new GTV. The new GTV knows about the old commands: it will detect these and suggest to the user what they should be replaced with. It can run in 2 modes, tolerant or strict, which can be toggled with the SIC variable GTV%STRICT2011. All the changes regarding these objects are exhaustively described in the appendix . The tables , , and summarize these changes.

Table: Old GTV and GREG commands which are removed or modified, their purpose, and their equivalent with the new GTV syntax. Refer to section  for a detailed description.
