This code works and doesn’t have the bug that we’re trying to avoid but there’s another way that looks cleaner. Remember thelocalfunction that you used to declare local variables until someone told you that you should usemyinstead? Well this is one of the few places where you can use...
Special variables are set by the system. They contain information of the current execution environment, such as the system clock, the logged in user, active locks, and etc. Most of them are read-only, and writing to them (such as withSETcommand) results in an error. ...
Two algorithms are proposed for computing a special function, dependent on two complex parameters, which has applications in electrodynamics and radio physics etc. The first algorithm is based on the use of quadrature formulae applied to the integral form of the function, while the second is ...
You can use keywords as ordinary symbols in many situations where there is no ambiguity. The precise rules are given here. There are three special variables: RC, RESULT, and SIGL.
I am writing an IAP loader and would like to locate it in the first 1024 Bytes of my CODE memory. How can I ensure this? I have tried to use wildcards, but this did not work out, since it collides with interrupt vectors. ANSWER ...
=SUMIF([Username],[@Username],G$2:G2) I'd hoped this would help, as with each row the end point of the range would change. But, when I use this function, it still sums the entire column G based on the criteria, not just from that range. A normal SUM function works the way ...
