This utility is used to correct record chain problems that affect indexes. Although the freechain is normally maintained through index maintenance and when expanding a file, this utility is also furnished as a separate utility program to repair the freechain pointer. This may be necessary when you receive an error message "Rebuild Freechain" or "Error in freechain".
Syntax:
For NIX
freechain filename [qualifier]
For Windows
freechn.exe filename [qualifier]
where filename is the filePro file name and [qualifier] is the optional qualified data set.
