XPEDIT Text Editor


Design Notes, Known Problems and Limitations


Design Notes

Prefix commands will be processed in the order in which they appear. The logic will validate and process until an invalid condition or combination occurs.

The first line on the logical file (Line 0) is the TOP_of_FILE. This is not an actual part of the physical file being edited.

The last line on the logical file is the BOTTOM_of_FILE. This is not an actual part of the physical file being edited. 

The editor will accomodate up to 1 million lines of text.

Known Problems

None reported.
