Re: file access problem.....

[booth@xxxxxxxxxxxx]

That question seems moot.  Non-unique keys are not a horrid thing but a 
lot of shops insist on some modifying field (like a sequence number) to 
make it possible to make a record identifiable and unique.  The RRN of a 
record does provide some uniqueness for it, so you can Setll on a 
non-unique field and then loop through records on a DOW loop that does a 
READE.  The INFDS will show you a record's RRN so you can update a 
particular record even if the key is non-unique.

My question is for any type of program...... 

accessing the file by a chain.........  the file is keyed but not unique

am I correct in assuming that the results would be unpredictable..... you 
would not always get the first added record by that key.......???
