FAL Usage Scenario
The FAL component of FX consists of the object module file fal.o (fal.obj for Windows
2000/2003/Windows NT systems) and the header file dataset.h. The FAL provides several
important C functions (Visual C++ for Windows 2000/2003/Windows NT systems) which enable
user applications on the open-system hosts to access z/OS data on the TagmaStore USP and NSC
FX volumes. There are two types of FAL, the 32bit FAL and the 64bit FAL. The latter is provided
by the TagmaStore subsystem.
