WHILE ... WEND
REPEAT ... UNTIL
SWITCH ... CASE ... ENDSWITCH
Loop is executed once, I=0 after loop. Loop not executed, I=1 after loop.
Variable name on NEXT Mandatory Optional, multiple variables allowed.
Function and position of END Executable command anywhere in program. Closes all files. Executable from keyboard.
