 As such, S/36 BASIC uses conventions that are no longer standard in modern BASICs, such as line numbers, and does not support newer features such as WHILE/WEND, DO/ENDDO, WITH/END WITH, procedures, properties, and so forth.BASIC interpreters written in the Seventies tended to "do odd things odd ways".For example, on the Apple II, a programmer could embed a command into a program via PRINT, when prefaced by the character string CHR$(4).
