STRING FUNCTIONS
ASC(X$)
This function will return the ASCII code of the first character of X$.
CHR$(X)
This is the opposite of ASC, and returns a string character whose
ASCII code is X.
LEFT$(X$,X)
Returns a string containing the leftmost X characters of $X.
LEN(X$)
Returned will be the number of characters (including spaces and
other symbols) in the string X$.
MID$(X$,S,X)
This will return a string containing X characters starting from the Sth
character in X$.
RIGHT$(X$,X)
Returns the rightmost X characters in X$.
STR$(X)
This will return a string which is identical to the PRINTed version of X.
VAL(X$)

operation from STR$. The string is examined from the leftmost character
to the right, for as many characters as are in recognizable number for-
mat.
