Today I am releasing a new beta of NBC and its highly popular high-level sister
Not eXactly C (NXC).
It is available via the NBC website (http://bricxcc.sourceforge.net/nbc/).
Be sure to also download the latest BricxCC test release for updated NXT support
for both NBC and NXC (http://bricxcc.sourceforge.net/).
Here is a bit of information about what is new in this release:
Version 1.0.1.b15
-----------------
- Adds to NXC new API functions:

Stop(bStop): Stop the program if the boolean expression evaluates to true
SetInput(port, field, value): Set an input field to the specified value
SetOutput(ports, field, value): Set an output field to the specified value
PowerDown(): Power down the brick immediately
RebootInFirmwareMode(): Reboot the brick in firmware mode immediately
BatteryLevel(): Read the current battery level (in millivolts)
FreeMemory(): Read the free flash memory (in bytes)
NumToStr(val): Convert the specified numeric value to a string
StrCat(str1, str2, ..., strN): Concatenate the args into a single string
SubStr(str, idx, len): Extract the specified portion of a string

- Adds to NBC new opcodes:
strindex dest, strsrc, idx: same as index but can take a constant string
strreplace strDest, strSrc, idx, strNew: same as replace but can take
constant strings
strlen dest, strSource: store the length of the input string into dest
shr result, value, n: shift right value by 'n' bits and store in result
shl result, value, n: shift left value by 'n' bits and store in result
- Adds to NBC a special compile-time operator:
sizeof(variable): returns the element size of the specified variable
- Adds to NBC a special compile-time opcode:
compchk comparecode, const1, const2: returns a compiler error if the
specified
expression is not true. For example: compchk EQ, sizeof(arg3), 1
- Adds '~' operator to the NBC compile-time expression evaluator (bitwise not)
- Fixes a problem in NBC (and NXC) with the RotateMotor API function
- Fixes a bug in NBC with nested preprocessor macro function calls
(e.g., FooBar(MyMacro(x, y), 2, 4)
- Fixes a bug in NBC with trailing spaces on #define values

 | | What do these macros do?
|
| I've been poking around with my NXT, and as usual I've decided to bite off more than I can chew. In trying to discover a way to *unset* pixels on the display without wiping the whole thing, I've been sifting through some of the less-discussed macros (...)
