Ken,

I think that many of us use  "Doesn't seem to work" not as a filePro problem
but in terms  that what we, the programmer, have written, does not work as
expected.  That includes using the wrong function or not quite programming
our process correctly.

I realize that this must be frustrating for you as you and many others see
what is wrong and try to guide the poster to the correct solution.

I have a feeling that most of us only use a small portion of the functions
that are available in the filePro programming language.  I know that I look
through the reference books I have to see if there are any functions
available that I have not used or haven't used in many years and forgot
about.  This includes Laura's help file and Stuart Werner's Developers
Reference Manual.  I have also been reviewing my original Xenix manual as
many of the programming suggestions used there are still relevant today.  I
still have my profile manual for 3.0 - 4.0 and the 4.5 supplement.
