A **variable**, also known as a **var**, can contain an integer value from 0 to 255, thus being the AGI equivalent of a byte (or unsigned char in C and C++). Variables are named by combining the prefix v with the number of the variable. There are 256 variables available in AGI, v0 to v255. The variables v0 to v26 have special meaning to the interpreter. You should not attempt to use these 27 variables for your own game data.

It is both possible and recommended to give your variables more meaningful names than a simple letter-number combination. This is possible using defines. The defines.txt file from the AGI Studio Template Game gives define names for the 27 special variables.
