Solved the issue.
i had use a new file name .
for instance i had just used the same file at @F and changed C-FLT to C-DEC . deleted file on disk and created a new one using pro4.
that did not work.
i copied the file to a new name in pro4 , created file and now the data displays on a pro4 screen... there is always a workaround. since i have 80 files to convert C-FLT to C-DEC i'm sure i'll find there is a way to get it done using existing pro4 file and just changing data type...
thanks again for the help, and if you have any other c-isam know how to pass on please post in the future.
