C/C++ Library for DOS 

This chapter describes the DOS software library, which is free supplied. The 
DOS library software includes a utility program, C language library, and some 
demonstration programs, which can help you reduce the programming work. 

To program in Windows environment, please use ACLS-DLL2.  The function 
reference manual of ACLS-DLL2 is included in the ADLINK CD. It needs 
license.
