VEE 4.01 Introduction Notes (jun 97)

last update 28 aug 98 / greg goebel / public domain / vwv_4_01

* This document provides introduction notes for the VEE 4.01 release in the early summer of 1997.

* The 4.01 release was strictly a bug-fix release and was the first VEE release that was implemented with the new patch technology.

Bugs from VEE 4.0 that were fixed in VEE 4.01 include:

• It was impossible to set any parity value on RS-232 except "none".

• The Instrument Manager would not refresh instrument settings if SICL was not installed.

• Compiling Formula objects took an amount of time proportional to the square of the number of terms in the Formula, making compile time extremely slow for certain programs.

• Error pin handling was very slow on VEE 4.0.

• Using Interface Event to perform SPOLLs hogged CPU cycles.

There were also a number of smaller bugs relating to the use of nil values in expressions; various odd ways to crash VEE (such as accessing the Toolbar while using DDE); and a number of cosmetic and documentation bugs.
