Choosing blank fields in Quiz (7.29C)

[Kim Williams]

I have a program that I wrote that the company has been using without any 
complaints for two and a half years.  One of the first statements is to "CHOOSE"
all the items in a subfile that have the field "FEDR" blank.  I wrote the 
statement as follows:

CHOOSE FEDR ""

It happens to be a six character item.  I probably should have written it as six
blank spaces between the quotes, but I thought it worked.  I think it probably 
did work at one time, because the result would have been pretty obviously wrong 
otherwise.  What actually happens is *all* the records are chosen.  I have 
printouts dating to this program's birth and it has always been this way so what
happened?  We haven't installed any Quiz patches in a long time (currently 
version 7.29C).  We have been regularly updating our MPE operating system so 
that has changed from time to time (C.55.00 and I think we are on powerpatch 4 
right now).

So do you think this *never* worked right and my users (and me) are 
spectacularly unobservant?  Or could something in my environment have changed 
and changed how my Quiz statement worked?

Thanks for any help,
Kim Williams
