be used to request system functions such as:
• Convert decimal numbers in ASCII format to binary values, and binary values to ASCII
format decimal numbers.
• Convert hexadecimal numbers in ASCII fomiat to binary values, and binary values to
ASCII format hexadecimal numbers.
• Provide I/O operations that are compatible with those for the DXIO operating system.
