Editing Apple III (section)

===Microsoft BASIC additional features===
*{{mono|INPUT$()}} function to replace Applesoft's {{mono|GET}} command.
*{{mono|LINE}} {{mono|INPUT}} statement to input an entire line of text, regardless of punctuation, into a single string variable.
*{{mono|LPRINT}} and {{mono|LPRINT}} {{mono|USING}} statements to automatically direct output to paper.
*{{mono|LSET}} and {{mono|RSET}} statements to left- or right-justify a string expression within a given string variable's character length.
*{{mono|OCT$()}} function for output, and "&"- or "&O"-formatted expressions, for manipulating octal notation.
*{{mono|SPACE$()}} function for generating blank spaces outside of a {{mono|PRINT}} statement, and {{mono|STRING$()}} function to do likewise with any character.
*{{mono|WHILE}}...{{mono|WEND}} statements, for loop structures built on general [[Boolean data type|Boolean]] conditions without an index variable.
*[[bitwise operation|Bitwise]] Boolean (16-bit) operations ({{mono|AND}}, {{mono|OR}}, {{mono|NOT}}), with additional operators {{mono|XOR}}, {{mono|EQV}}, {{mono|IMP}}.
*Line number specification in the {{mono|RESTORE}} command.
*{{mono|RESUME}} options of {{mono|NEXT}} (to skip to the statement after that which caused the error) or a specified line number (which replaces the idea of exiting error-handling by {{mono|GOTO}}-line, thus avoiding Applesoft II's [[stack (abstract data type)|stack]] error problem).
*Multiple parameters in user-defined ({{mono|DEF FN}}) functions.
*A return to the old Applesoft One concept of having multiple {{mono|USR()}} functions at different addresses, by establishing ten different {{mono|USR}} functions, numbered {{mono|USR0}} to {{mono|USR9}}, with separate {{mono|DEF USRx}} statements to define the address of each. The argument passed to a {{mono|USRx}} function can be of any specific type, including string. The returned value can also be of any type, by default the same type as the argument passed.

There is no support for graphics provided within the language, nor for reading analog controls or buttons; nor is there a means of defining the active window of the text screen.
