Greetings! As a few people have been posting about, I have a library
that allows you to manipulate IDL SAVE files. Up until now, this
capacity has been limited to reading and writing IDL *variables* (data
only).
Allow me to announce the first major upgrade to my library, which
allows you to read and translate saved IDL *procedures*.
As of 2002 Mar 22, four new routines are included which can translate
compiled procedures from SAVE files, back into human readable form.
Now if you have lost the source code to a compiled save file, or if
you just want to see how things work, you can translate the save file
back to a format familiar to you!
The main routine of interest is the simple driver routine called
PROTRANS, which will translate compiled code from IDL SAVE files into
and IDL-like format. As usual all files contain full documentation in
their program headers. I have anticipated a few frequently asked
questions too, so go ahead and read those. :-)
As far as I am aware, PROTRANS (and underlying library routines PRODIS
and PROREND) is capable of translating *any* saved procedure or
function created by IDL 4, and IDL 5.0 through IDL 5.5, *except* that
it does not handle compressed files. [ Although this is easily
remedied by restoring and resaving in non-compressed form. ]
***
In a separate development, I have also posted extensive documentation
of the format of IDL save files (variables only). While I anticipate
that the interest in this document will be essentially zero, I felt it
was important to document the knowledge. This may especially help
users from other languages to read and write IDL save files.
Enjoy!
Craig
