DOS function calls/pseudo calls Internet Basic programs can make direct calls to the Disk Operating System (DOS) via the following statements:

DOSFC

DOSRW

DOSMS

See DOS Calls Background Discussion for more information.

Also see Pseudo DOS Functions.

Note: These host system function calls are very powerful interfaces to the DOS environment. They require care and good planning to be used effectively. Since this document does not pretend to be a substitute for complete DOS documentation, we recommend that you refer to the DOS Technical Reference Manual before implementing these functions in your Internet Basic programs.

It is the responsibility of the programmer to ensure that any file handles opened are closed upon completion of the desired function. Failure to comply will result in degradation of system performance and possible system hangs.

The following DOS function calls are included in this document:

Change Current DOS Directory Close DOS File Create DOS File Create DOS Subdirectory Erase DOS File Get DOS Date Get DOS Time Move File Read/Write Pointer (LSEEK) Open DOS File Read From a DOS File Remove DOS Subdirectory Write to a DOS File
