Are there industry-standard definitions for the terms "block valve" and "control valve"?
I tend to think of block valves as OPEN/CLOSE (binary) service and control valves as throttling service.
Many of my colleagues use "control valve" when an OPEN/CLOSE valve is intended. As we are...
I used the subject macros extensively in a previous project.
But now, several years later, Excel does not execute them in my new project and VBA Help does not acknowledge their existence.
Am I correct in assuming that MS killed them in XP for security reasons?
