0).

The example below prompts for a positive value for SIDES,

modifying an earlier program in this chapter:

REPEAT

INPUT(SIDES,"Die Sides","N = ","Enter

num sides",2);

UNTIL SIDES>0;

END;

loop.

user-defined variable.

Syntax: LOCAL var1,var2,…varn;

Makes the variables var1, var2, etc. local to the program

in which they are found.
