That was never a problem when I was actively programming, and I believe that was extended as part of their adoption of OOP with version 5.5+. Back in those days, testing was performed by setting up instruments with string commands, then triggering them with events generated by the test code. Reports were collected by reading instrument registers, so string length was never an issue. I was happy with the introduction of named Calls at the time, as everything the company I worked for used procedure calls that had numbers, and the only way to find out how to call them with parameters was to beg the Systems Programming group for documentation on a particular Call. Strange times, and everything was proprietary and dynamic; it wasn't unusual to use three programming languages on one Project. We are so very much better off today!
