Qedit Workfiles
The Qedit workfile provides both random and sequential access to variable-length lines of text. The file code is 111, the file is Binary, and the block factor is 1. The workfile is broken into blocks. Each block contains several Qedit lines (the exact number depends on the length of the lines). The lines in a block have contiguous line numbers and are extracted from the block by Qedit.
Block 0 of the workfile has a special format because it contains the control and indexing information.
The first Qedit line is always in block 1, and the start of block 1 points to the next sequential block in the file, which need not be block 2. Each block points to the next, and end-of-file occurs when the forward pointer is zero.
There are three different formats of Qedit workfiles: original, Jumbo, and Wide-Jumbo. All formats work in Qedit for MPE and Qedit for HP-UX, but the default for MPE is the original format while the default for HP-UX is Wide-Jumbo.
