Casio PB-120
Another nice Casio calculator, a BASIC programmable, the PB-120 is similar in style and appearance to the PB-110. One major difference: instead of a measly 544 bytes of memory, the PB-120 has a whopping 8 kilobytes. Now that's what distinguishes a toy from a genuinely useful device! In 8 kilobytes, serious programs can be written, including programs that manipulate larger arrays of data or perform sophisticated scientific or technical calculations.
My example program is a great deal less ambitious: it is just another variant of my favorite programming example, the Gamma function.
10 INPUT X 20 G=1 30 IF X>5 THEN 70 40 G=G*X 50 X=X+1 60 GOTO 30 70 G=X*LN X-X+LN (SQR (2*π/X)/G) 80 PRINT G+((((1/99/X/X-1/140)/X/X+1/105)/X/X-1/30)/X/X+1)/12/X
