ReadHex16Test

Notes: A screenshot of a terminal window showing the output of a function for testing the ReadHex16 subroutine of the HexDump program. The window has a series of repeated four-digit hex numbers with a blinking cursor at the end of the third line. The first number can be a lowercase or uppercase letter but the second number is always uppercase. The program uses the RedHex16 to read four digits entered with the keyboard and then uses PrintHex8 twice to repeat the number back. There are no non-hex digits as those get ignored by the program.
