General EQWatcher Concepts > Venturing into the Unknown  > Pre-defined values

Constant integer values the compiler (and only the compiler) understands

true   (equal to 1)
false  (equal to 0)
SND_WAVE  (the rest are arbitrary, you don't need to know the actual value)
SND_CD
SND_MP3
SND_TTS
SND_SYNCWAVE
SND_SYNCTTS
 

true and false are intended for use with boolean variables, for making them easy to use.  When a boolean variable is converted to string data, for use in text-to-speech or otherwise, the data becomes "true" and "false"

The SND_* values are intended for use with timer and trigger adding functions.

These integer values are all identifiers.  You may read about those in the appropriate sectoin.

Variables the interpreter reserves

The only pre-defined value that can be used as a variable name referenced between %'s in triggers or aliases is "clock" which is equal to the current value of a clock() call (see the miscellaneous built-in functions).
