The long statement is used to define one or more variables and arrays of type long. The long statement behaves in the same way as the int statement, the only exception being that it reserves 32 bit memory locations instead of 16 bit memory locations. 32 bit variables of type long are used to store numbers in the range -2,147,483,648 to +2,147,483,647BEWARE: like the int statement, the long statement is used to define both local and global variables depending on the context in which it is used.
e.g. long var1 long var1, var99[10], var3
