You have either used a verb in the Procedure Division of your program that your COBOL system does not recognize as a valid COBOL verb, or have misspelled a COBOL verb.
Resolution:
Chech which verbs are permitted in the COBOL language, and ensure that you have spelled them correctly.
You might need to set a language-enabling directive if the verb you require is not part of your system's standard COBOL language.
