Three editor functions have been added to HTBasic and should not be used in programs that will be executed with HP BASIC: DEL LEFT, NEXT WORD, and PREV WORD. Otherwise, all the two-character function key sequences (CHR$(255)&CHR$(X)) used by HP BASIC are compatible with HTBasic. If multiple statements are output in a single OUTPUT KBD statement, they are all executed before the next BASIC line. HP BASIC sometimes intermixes the execution with multiple BASIC lines, based on the presence or absence of "closure keys."
