Line 30:
Also akin to MS BASIC, 16-bit [[Signed number representations|signed integer]]s (i.e. in the range -32768 to 32767) were available by postfixing a variable name with a percent symbol, and string variables were represented by postfixing the variable name with a dollar sign. Despite the 2 character limit on variable names, the variables <code>AA$</code>, <code>AA</code>, and <code>AA%</code> would each be understood as distinct.

Many BASIC extensions were released for the Commodore 64, due to the relatively limited capabilities of its native BASIC 2.0. One of the most popular extensions was the [[DOS Wedge]], due to its inclusion on the [[Commodore 1541 Test/Demo Disk]]. This 1 KB extension to BASIC added a number of disk-related commands, including the ability to read a disk directory without destroying the program in memory. Its features were subsequently incorporated in various third-party extensions, such as the popular [[Epyx FastLoad]] cartridge. Other BASIC extensions added additional keywords to make it easier to code sprites, sound, and high-resolution graphics like [[Simons' BASIC]].
