# Sequential/Random Access Files Support Package

RAM-based LKDOS extension adds support for sequential data file support to BASIC commands.

Lets you create, read from, or write to very large data files kept on disk. It uses the commands OPEN#, CLOSE#, PRINT#, INPUT#, and INKEY$# to access the files from BASIC. There is also a high speed search command for finding a text string within the data file. Using the TAB command, you can randomly access directly any record in a file.

The utility is easily used within BASIC programs and has a lot of uses, from storing large data files, creating large spell checker dictionaries or even converting you BASIC programs to an ASCII text file.

Takes the limits off of the data capacity of the 2068.

A simple data base program is included on the disk to demonstrate the utility.
