Clear all files

Syntax

Clear all files

Description

This command clears the current record buffer of all file variables for all open libraries and all open data files, including any memory-only files. However, it does not clear the hash variables. Window instances are not automatically redrawn so you must follow it by Redraw if you want the screen to reflect the current state of the buffer.

This command is reversible for read-only and read-write files; the command reverses by re-reading each record into the current record buffer. Note that using this command in a reversible block with a memory-only file will clear the current record buffer for that file when the command reverses.

Example

# Clear all file variables from the current record buffer and
# redraw the current window instance 
Clear all files 
Do  $cinst.$redraw()
