ABSTRACT

Safe I/O

This generic package allows the user to input data types from the keyboard while checking the input for errors. (Proper Type: syntax and ranges.)

A procedure for checking input of characters for a proper subrange of the character set is provided.

When an error is encountered, an error message is displayed and the user is allowed to reenter. Output routines are provided to allow the user to do I/O with only one instantiation. Screen manipulation (i.e. NEW_LINE) should be done with TEXT_IO directly.

Instantiations require a FIELD_WIDTH which specifies the maximum field width for the input of the corresponding type.
