Program design tips

  • Use industry-standard tools.
    • Use a C or C++ compiler adhering to the ANSI standard. If you are using the API under Windows, use Microsoft Visual C++ (version 6.0 or later).
    • If the program must run on both UNIX and Windows, use POSIX routines for system calls.
  • Use variables (instead of hard coding) for more flexibility and less maintenance.
    • Use symbolic constants (#define values from ar.h).
    • Use environment variables.
    • Use files to store menu or selection values instead of writing them into your program.
    • Minimize network traffic.
    • Use bulk transfer to retrieve data and to cache the information locally. Omit unnecessary fields when retrieving data.
