Showing and Operating Within a Text File

3.11 Showing and Operating Within a Text FileÐthe Show Command

Use the show command to show a text file. This command uses the entire screen below the second line as the file display window. When you select the show command, the programmer prompts for a file name:

File:

Type the pathname of the file to be displayed. If the file exists, the programmer displays the first lines of it on the screen.

The maximum size of a file that can be displayed is 2048 lines. Any file larger than this is truncated to 2048 lines. The maximum file size is also limited by available memory because the entire file is PC memory-resident.

Table 3±4 gives the commands, functions, and control keys available for in- specting the text file. The letters used to invoke the command are printed in bold type.
