There are two copies of STARTRK these will only work if you have the two PROMs for TinyBasic installed. The second one includes TinyBasic extended functions of PEEK, POKE and SAVE. Look at the SAVETB.ASM file to see how these functions work. If you have the TinyBasic ROMs installed, you can load this file and start a new program by the NEW command. Any future programs will keep these fuctions when saved with SAVE.
