These are 'Windows' versions of the equivalent standard C library 
functions. There work on zero-delimited bytes in RAM, which is how C 
expects strings to be stored.

 lstrcat(a,b)  -- Concatenates b onto a. Returns a.
 lstrcmp(a,b)  -- Compares a to b. Returns -1, 0, or 1.
 lstrcmpi(a,b) -- Case-insenstive compare.
 lstrcpy(a,b) -- Copies b to a, replacing a. Returns a.
 lstrcpyn(a,b,n) -- Copies b to a, but no more than n characters.
 lstrlen(a) -- returns length of a.

In each case above, 'a' and 'b' are RAM addresses. It is you responsibility 
to make sure that the buffer size is big enough for lstrcat and lstrcpy to 
work.
