Knowing the bit patterns of a specific byte can also help to better understand machine code among the many other uses. The following BASIC program will print out all 256 bit patterns, their hexadecimal and decimal equivalent.

Here are two commands found in other computer BASICs which are missing from Sinclair BASIC. They are GET and PUT, and are used transferring screen images.

Sinclair BASIC graphics commands PLOT and DRAW have several disadvantages and shortcomings. One of them is that they only address a 256 X 176 pixel screen and cannot draw to the bottom two character lines.

Read the output of CAT via SCREEN$ and load programs.

Program uses the SCREEN$ function to facilitate loading software from a Larken disk system.

Lotto number generator that can be modified for your geographical requirements.

Did you ever do a lot of repetitive keying or wish you had programmable function keys? Here’s a clever little utility which will do just that. It was originally written for the Spectrum and uses the interrupt mode 2.

One of the “must have” utilities that any self-respecting software “hacker” needs in his/her arsenal of tools is a DATA line maker. Although there are several available, especially for the Spectrum ROM, mv favorite one appeared in the May 1988 newsletter of the Capital Area Timex Sinclair Users Group by H.E. Weppler. I have simplified…

The following bit of machine code will allow you to print any text string using a clean, fast 64 column character set. What distinguishes this program from similar ones is that instead of requiring 768 bytes to define the characters (96 characters X 8 bytes per character), this program uses half the usual number of…
