You may be able to work around this by using parenthesis (untested).
a = ((x * 100) + y);
or you might try
a = 0 + ((x * 100) + y);

| (...) Neither of these work, although the second one does introduce a temporary for everything except for the 0 part. It will result in the display sometimes showing a value of zero. NQC tries really hard to use as few variables as it can so you (...) (21 years ago, 5-Jun-05, to lugnet.robotics.rcx.nqc)

| (...) Thanks for the ideas! Actually these yielded some interesting results: a = 0 + ((x * 100) + y); occasionally yielded 0 (as expected), but never yielded anything other than 0 and the correct value (that I saw). a = ((x * 100) + y); and a = (x * (...)

| I have a program with a setup routine for calibrating light sensors. During the setup routine, it does: SetUserDisplay (a, 2); Then in a loop, reads the values of 2 light sensors into x & y, averages the readings and then does: a = x * 100 + y; to (...)
