LINE INPUT Avoids INPUT Statement's "Redo from Start" Error (31161)

SUMMARY

To avoid the "Redo from Start" error message encountered when incorrect input is entered in response to an INPUT statement, use the LINE INPUT statement instead. (The INPUT statement's "Redo from Start" error message cannot be trapped or handled with the ON ERROR GOTO statement.)

However, because LINE INPUT accepts all characters until it encounters a carriage return, you must parse the input string yourself using string manipulation (for example, MID$, INSTR) and type conversion (for example, VAL).
