Hi John,
Richard answered your question #2 a little while ago:
: To: acedb at net.bio.net: From: <rd at sanger.ac.uk>
: Subject: Pick_me_to_call in 4_1
: Date: 31 Aug 1995 19:23:26 +0100
:: There has been some discussion about where Pick_me_to_call looks for
: files. In the 4-8 worm distribution we used Pick_me_to_call for JPEG
: pictures. Instead of making the second argument "xv" directly, we set
: it to be the name a script in wscripts/, "display_script", which
: explicitly specifies the directory in which to look:
:: xv $ACEDB/pictures/$1 &
:: This is preferable to changing directory in the script with which you
: invoke acedb, because it is nice to be in your own directory for
: writing out files. It also allows people to change the way xv is
: invoked, e.g. set options, or change to another image viewer, without
: editing the database.
:: Richard
Apparently Pick_me_to_call now executes the first tag-value, passing it the
second tag-value as $1, along with the current environment. $ACEDB/wscripts
is placed at the front of the process's $path. This is a lot more flexible
than the old behavior. Maybe it will help with question 1.
