File permissions when using processing tables

[Matt Hersant]

I've a question regarding file permissions when using filepro processing 
tables.  We've an input processing table which runs when a data is input 
into a filepro file.  During this process, the fp code makes a system call 
to append data to a text file, or uses sed to substitute in new data.  When 
all is done the permissions of the text file have been changed to the Unix 
account of the person who updated the filepro file.  I can't seem to figure 
out why this is happening.  No chown is being called by the processing 
table.  The file permissions are 666, so that it can be updated by anyone.  
Any help or advised is appreciated.
