I have just heard the dreadful news about Dan Baronet. My thoughts go out to his family and friends, and to those who worked with him.

We will miss you. Rest in peace.

This is supposed to be a simple application of searching and replacing text that has been generated by OCR. As you know, OCR is not perfect, and there are lots of false readings, perhaps influenced by a built-in spelling dictionary. When the language you are OCR-ing from is not the same as the ...

As someone who has used A+ in anger, I would like to recommend to you the concept of the "slotfiller". Obviously I'm not going to suggest it be added to APL exactly as it is in A+, but it is a useful concept which would make some APL processing much simpler.

Every application should have its own session log file, to avoid losing what happened last time something was done in application xxx when you have been enhancing application yyy for the past week or so. My idea was to change the log file on the fly, and read the new logfile in, replacing what was ...

Thanks, Ray, that's helpful. What I was hoping to do was load the session-log file under program control whenever a different workspace is loaded (or the default one if one named after the workspace doesn't exist), and maybe also save it at regular intervals so that I've got some stuff from my ...
