This paper presents an FFT‐program written for the use of the programmable pocket calculator of Texas Instruments TI 59. The program consists of the following routines: Input/output; FFT forward and inverse; shuffling and a routine that converts the FFT‐coefficients in case that real numbers were put in. The maximal number of input data is 32 complex or 64 real data. Listings of all routines are given and the program handling is described. Peak sharpening and removal of background (PARG) are examples to demonstrate the handling of routines.
