only 48 KB of memory: BASIC.COM would then have about 23 KB free for user code, whereas BASICA would have only about 17 KB. By 1986, all new PCs shipped with at least 256k, and DOS versions after 3.00 reduced Disk BASIC to only a small stub that called BASICA.COM for compatibility with batch files. Even with all this excess RAM, BASIC would still allocate and manage only about 61 KB for user programs, whether it was
Cassette BASIC, BASIC.COM, or BASICA.

However, Cassette BASIC was rarely used because few PCs were sold without a disk drive, and most were sold with PC DOS and sufficient RAM to at least run Disk BASIC—many could run Advanced BASIC as well. There are three versions of Cassette BASIC: C1.00 (found on the early IBM PCs with 16–64K motherboards), C1.10 (found on all later IBM PCs, XTs, ATs, and PS/2s), and C1.20 (found on the PCjr).

Disk BASIC can be identified by its use of the letter D preceding the version number. It adds disk support and some features lacking in
Cassette BASIC but does not include the extended sound or graphics functions of BASICA. The primary purpose of Disk BASIC was as a "light" version for IBM PCs with

Compaq BASIC 1.13 was the first standalone BASIC for the PC (that did not require

BASICA versions are the same as those of their respective DOS, beginning with v1.00 and ending with v3.30. The early versions of BASICA did not support subdirectories, and some graphics commands functioned slightly differently. As an example, if the
