I'm using NQC on NT and have downloaded the latest pbForth: 1.1.1 I'm invoking NQC with: "nqc -firmware pbforth.srec" I get the dots crawling across the command-prompt window.

Efficiency of "if" vs. "switch" can be very dependent on the compiler and the CPU (...) (24 years ago, 31-Mar-01, to lugnet.robotics.rcx.nqc)
