Qbasic/QuickBasic Programming

CRC32.exe and CRC Table.exe have now been ported to B64 Windows executables. CRC32.exe calculates the CRC32 "check sum" of a file which will show if a file has been changed/damaged and/or incorrectly transmitted/received. It also has the unique ability to calculate the CRC32 value of a typed-in string within the program; and even the ability to then reverse the string for a new CRC32 value. If you select the WinZip/PKZip Seed, CRC32 will compute the same CRC32 value for a file that DOS PKZip, WinZip, 7-Zip, and Windows Explorer calculates. You can also find the CRC32 value for a string as well as the CRC32 value for the same string with every byte reversed. CRC32 Table is a program that displays the complete CRC Table for a given Seed. Both programs can also be started with any custom Seed for totally different results. For those who are interested in CRC32 math and theory, a duplicate historical document published on the web in 1993, CRC Error Detection.html, is also included.
