/* Edit a SOURCE or NOTE file from Origins */
/********************************************/
/* NOTE:
This file is the same as EditGen.rexx, except it specifically calls Ed as
the editor of choice.
To function correctly, this script must be renamed EditGen.rexx and copied
to the REXX: directory.
This script will attempt to load the SOURCE or NOTE file requested by
Origins into Ed. The function may be blocking or non-blocking by your
choice. As written, the function is non-blocking.
When Origins calls this script, it does so in a blocking manner; the
program won't continue until the script returns. If you wish this
behaviour, make the script block until you are done with the file.
Otherwise, make the script return immediately.
Since Ed doesn't do a ScreenToFront() when called, you'll have to
switch to the Workbench screen to see it.
There appears to be a bug in Ed such that when you load an existing file,
and then load a new file, Ed returns error #3 (Insufficient memory).
This does not seem to cause any harm; the file is still created OK. We
just thought you'd like to know this.
