a program written in one of these BASICs could only be listed and run if the user had that BASIC. However, compilers and run-time executables started to appear for these BASICs that produced executable code that could run on all STs, and type-in programs became less fashionable, so there was no longer a need for a standard BASIC. By then, HiSoft BASIC, Omikron BASIC and STOS BASIC had appeared. Some of these BASICs even started to be bundled with new STs in the later years.
