CKSM.CO is a modified version of QKRCHK.200 that will run with XOS. Use HXFER to create CKSM.CO and keep in bank #3. Place cursor over .DO file and press F3. CKSM will run CKSM.CO found in bank #3. You will remain at the Menu and the checksum of the cursored .DO file will appear where the word "Length:" would normally be found. The checksum information will remain in view until the wide-bar cursor is moved to another file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
