******************************************************************

    SoftWeyr enhanced DOS ToolBox is a huge library, containing
more than 64 procedures and functions which covers varios kind
of file handling, memory management on DOS level etc etc.
    It can be used either in simple command-line controlled programs,
or in sophisticated TurboVision applications.
    It is designed for real usage in real programs. Most procedures
are written on assemble language (but not inline assembler, therefore
it can be used it Turbo Pascal prior 6.0)

    It covers following topics:

1. General purpose file handling without usage of file variable.
2. Increasing count of availiable files
3. Standard input/output, including STDERR, SDPRN
4. Duplicate output to screen/TV window to file/printer
5. Output with pause after each n lines invisible to your program.
6. Really international UpCase
7. Allocation/deallocation DOS memory, including UMB
8. Environment handling, including returning values to parent process
9. Text file positioning
10. Switching between A: and B: on single drive system
11. Checking redirection of input/output.
12. Temorary files
13. Treating memory blocks as text files
