BASIC and although
* Despite its heritage, Applesoft lacked commands common to most other Microsoft BASIC interpreters, such as INSTR ( which searched for a substring in a given string ; this had to be done manually with loops and the MID $ function ), PRINT USING ( which formatted numbers with commas and currency signs according to a format string ), and INKEY $ ( which checked for a keypress without stopping the program as Applesoft's GET command — analogous to the INPUT $ function — did, although a PEEK location did provide this functionality ).

It was a rather simple but powerful BASIC implementation by the standards of the day, featuring dedicated commands for handling graphics ( such as DRAW, PLOT, INK, and PAPER in all versions ; plus FILL in v1. 1 ), even allowing the creation of multiple screens, windows, and the like, although the color system and palette handling was awkward.
The HP 9810, 9820 and 9830 desktop computers used a slow, serialized TTL version of the 2116 CPU, although they did not ultimately use any of the operating system or application software, instead relying on user-friendly ROM-based interpreters such as BASIC which worked when powered up and integrated keyboards and displays rather than disks or standard terminals.
The two computers were notably similar, although the ZP-150 did include BASIC and could be configured with more memory, but did not have a built-in diskette drive.
Each BASIC statement had to be on a uniquely numbered line, e. g.: 10 PRINT " HELLO WORLD " and could only contain one statement, although multiple variable assignments were allowed, e. g., 20 LET A = B = C = 42
This is in sharp contrast to some other BASICs that use functions such as LEFT $(), MID $(), and RIGHT $() to access substrings, although ANSI BASIC continues to use a similar substring syntax to that introduced by Hewlett-Packard.
* In relation to macros, Calc's BASIC functions are basically like those of its competitor, although it lacks a few of them, like InStrRev ( which reversely looks up a substring within a string ).
