The HP COBOL extensions are considered unsupported by ACUCOBOL-GT when recognized at compile time but ignored at run time. Such extensions, when present, cause the compiler to return a warning message indicating that this is an unsupported operation. They do not prevent the compiler from creating an object.
The following HP COBOL extensions are not supported by ACUCOBOL-GT in HP COBOL compatibility mode:
COBOLLOCK
COBOLUNLOCK
EXCLUSIVE
UN-EXCLUSIVE
