 Commands

• TX0, TX1 - Abbreviation for the window, and the text window number. Currently, up to three text windows may be defined. The current text window is indicated by flagging the window abbreviation in half-bright inverse video. In this example, TX1 is the current text window.

• COL - The column number at which the window is aimed. Text windows may be "shifted" to view data that would otherwise be off the end of the screen.

• LINE - The line number (file record number) at which the window is aimed.

• FNAME - The name of the file at which the text window is aimed.

• text - The ASCII contents of the text file(s).

• "." - Dots signify lines past the end-of-file count.

• "x" - X's signify an error while reading the data for that line. This could be a protection violation or some other cause (not shown above).
