In HP COBOL compatibility mode, ACUCOBOL-GT supports the use of the CREATEPROCESS intrinsic function to start separate, directly executable programs. CREATEPROCESS statements that launch such programs do not have to be modified in any way. CREATEPROCESS statements cannot, however, be used to start programs that have been compiled with ACUCOBOL-GT. Such programs can be started directly with the CALL or CALL RUN statement. Existing CREATEPROCESS statements that call programs that are now compiled with ACUCOBOL-GT, must be converted to use the CALL or CALL RUN statement.
