[comp.databases] Paradox PAL canvas

orrissd@csusac.csus.edu (David Orriss) (09/22/90)

Hi!

  Can anyone tell me what the 'PAL canvas' is all about in Paradox?
Is there a particular part of the documentation that will describe
it to me?  Thanks!

From the PAL User Guide glossary (se also Chapter 13):

	The screen you see during the playing of a
	PAL script.  When a script begins, the canvas is
	initialized with the scene present on the Paradox
	workspace.  While the script is being played, the
	canvas hides the workspace unless the script
	explicitly calls for the user to view it.

RTFM :-)

The canvas is where you "paint" prompts for user input or display messages to
the user.  The canvas is lifted and dropped in front of the Paradox workspace
which is where table and query images are displayed and worked on.  The canvas
hides the workspace unless you explicitly tell it not to with the ECHO command.
Page 150 of the PAL User's Guide explains the canvas in detail.
