When your ACUCOBOL-GT program is ready, compile it using the "-D5" data format switch. This causes data items declared as BINARY to be treated as COMP-5. This means that the data values are stored in the host machine's native byte-order instead of the machine-independent byte-order normally used. Such data items can contain values of magnitude up to the capacity of the native binary representation (2, 4, or 8 bytes) instead of being limited to the value implied by the number of 9s in the picture. The runtime will not require any special switches to use the IBM library routines or COPY files once you have compiled with this option.
Use caution when compiling with any other "-D" flags because this could cause problems in compilation
