BASIC-DOS Commands

BASIC-DOS has a single command processor for both DOS commands (eg, DIR) and BASIC statements (eg, PRINT), so any command can be typed at the prompt or used in a BASIC program. Commands are organized as follows:

BASIC Commands: statements for variables, control flow, error handling, and memory
BASIC Functions: numeric, string, and system functions, and predefined constants
Device Commands: clock, keyboard, screen, graphics, and sound
Disk Commands: copying, deleting, listing, loading, and displaying files
External Commands: COM, EXE, BAT, and BAS programs
System Commands: help, memory, program management, and system control

In the descriptions that follow, italics indicate values that you supply, brackets ([ ]) indicate optional items, and a vertical bar (|) separates alternatives.
