10 'PRNCHECK.BAS - A program to print selected checks on the printer
20 'From the GW-BASIC Tutorial Series (GWBT04 homework from 09/15)
30 '
40 'A Reminder: Our CHECKS.DAT format is as follows:
50 '
60 'CHECKNO Six characters containing the check number
70 'CHECKDATE Ten characters containing the check date (mm/dd/yyyy)
80 'CHECKPAIDTO Fifty characters containing the payor of the check
90 'CHECKAMOUNT Ten characters containing the amount of the check (nnnnnn.nn)
100 'CHECKMEMO Forty characters containing the memorandum field
110 '
120 'What we need to do is get the desired starting and ending check numbers
130 'from the user, then check each record in order to see if it falls between
140 'the desired range and print it if so.
