The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

■ The DO keyword that starts a DO...LOOP statement is missing
  or misspelled.
 
■ Possible solutions:
 
  • Insert the DO keyword at the beginning of the DO...LOOP
    structure or correct misspelling as necessary.
 
  • Check other control structures within the DO...LOOP block
    to verify that they are correctly matched.
 
■ If you need additional help, move the cursor to a keyword
  and press F1 to open the Help window.
