A pocket computer was a 1980s-era user programmable calculator-sized computer that had fewer screen lines,  and often fewer characters per line, than the Pocket-sized computers introduced beginning in 1989. Manufacturers included Casio, Hewlett-Packard, Sharp, Tandy/Radio Shack (selling Casio and Sharp models under their own TRS line) and many more. The last Sharp pocket computer, the PC-G850V (2001) is programmable in C, BASIC, and Assembler. An important feature of pocket computers was that all programming languages were available for the device itself, not downloaded from a cross-compiler on a larger computer.
The programming language was usually BASIC.
