| MID$ Function | Reference/Commodore BASIC V3.5
MID$(X$,S[,X])
This function returns string data.
This function returns a string taken from X$, containing X number of characters starting from the Sth character in X$. If X is not specified, all characters starting from the Sth character to the last character are returned.
The MID$ function can also be used to change parts of a string by being used as the left side of a LET statement. When used in this way, the value of X (if present) is ignored, and the length of the string on the right-side of the LET statement must not exceed the length of X$ minus the value of S. If this happens, an ?ILLEGAL QUANTITY ERROR will occur.
MID$("THE CAT IN THE HAT",5,3) Returns the string 'CAT'
A$="THE DOG IN THE HAT": MID$(A$,5) = "CAT" Changes A$ to 'THE CAT IN THE HAT'
