I defined a global variable in bool type but the compiler gave me a
parse error on it. There seems no "true/false" either, but has to be
"TRUE/FALSE". The word "bool" shows as a key word in blue color. Does
vxWorks support the bool type? Thanks!

only in C++ language files.  The 'C' language doesn't know the words
'bool' 'true' or 'false'.

More accurately, the 1990 C standard doesn't "know" these words.  In
the 1999 standard, they defined as macros in <stdbool.h>
