"CASText" Text Converter for CASIO Pocket Viewer model PV-100.

This program is a free software. License agreement see below. This program breaks text onto blocks by 2048 bytes. This allows you to import processed file into notes in PCSync provided with CASIO PV-100. It allows you to put lengthy text into CASIO PV-100 and use it as a bookreader. Though it is still unuseful to read 5 pages then switch to another block, but it is much better than standard import tool (usually 80 characters), and more over it is a PV-100 limit: 2Kb per block.

Upper half of charset is processed as Russian.
