Version 1 runs without problems, but I got this error while running version 2 :
D:\Gnuproject\bin\LAB2.exe
libcob: error: version mismatch
note: LAB2.cbl has version 2.0.0
note: libcob has version 3.1.2.0

Process finished with exit code 1

What can be the problem?
Thank you and best regards,

Answer 1

The error message suggests a version mismatch between the program "LAB2.cbl" and the Cobol compiler "libcob". The LAB2.cbl file has version 2.0.0, while the libcob version is 3.1.2.0. To resolve this issue, you may need to ensure that the versions of both the program and the compiler are compatible. Updating either the program or the compiler to a compatible version should resolve the error.
