Items may be either numeric or string expressions, and may be separated by commas, semicolons, or nothing. Otherwise, a question mark is printed. The computer then waits for values for each variable to be entered. If several variables are listed, their names must be separated by commas. If the variables are numeric, their values may be entered on separate lines, or combined with commas.
Any numeric expression is a valid response.
If the variables are strings, each string is typed on a separate line. The characters typed are copied verbatim into the string. The line number may be any numeric expression. The word GO TO may be used instead of GOTO if preferable. Otherwise, the statements following ELSE are executed.
