Free MS-DOS utilities

eval100.zip

EVAL is a small scientific calculator to be used from the DOS command line or in batch file processing.

1. EVAL is free.
2. All calculations are performed in long double precision (80 bits).
3. It can evaluate any expression (or set of expressions) located in its command line (useful for fast calculations and inside batch files)
4. It can also be used as an interactive calculator.
5. You can assign values to variables and use them.
6. It has a complete and easy to use help file.

XSORT (and its 16 bits version SORT) is a yet another sort/merge utility! You could consider using it because:

1. XSORT is free.
2. The SORT utility that comes with every DOS copy is very slow and can handle only very small files.
3. XSORT is more powerful than all other shareware/freeware sort programs I have been able to test.
4. It is a true 32 bits program, so it runs quickly and is able to use all the conventional/expanded/extended memory to deal with large files. After using all the memory, the disk will be used as virtual memory. Even the 16 bits SORT, which can be used in any compatible computer, will use the disk to handle large files.
5. XSORT can use different sorting algorithms ranging from the fast Quicksort to the stable Insertion sort.
6. It can be used to sort files using the PC or the Windows ANSI character set.
7. It can be used to sort correctly non-English files.

These programs are copyrighted material (see the copyright notice in the documentation for each program). But you can freely use and distribute them. You cannot sell them.

All these files, except unzip.exe, are compressed. To decompress them you need PKUNZIP 2.04g or another compatible program, such as unzip.exe which is available here.
