in thread xs modifying passed value

I always get em backwards

Easy: If you want to compare characters (strings, char* or char[] if you know C), use the operators made from characters (eq, ne, lt, gt, le, ge, cmp). If you want to compare numbers like in mathematics, use the operators you know from mathematics (==, !=, <, >, <=, >=, <=>).

[stevieb]: I don't know what you mean. I write the code in C/C++ that accesses the ICs per the datasheet, wrap it for Perl, then use them. My code ensures that the functions/methods from Perl do the right thing for the chips/sensors etc
[stevieb]: At least that's what I'm working on right now. I've also been updating my automated test software Test::BrewBuild so it handles this work properly. It's not really easy meshing high level languages with low-level hardware :)
[stevieb]: this link is probably better for an overview of my test software
