i have a physical file i need to update that file (not append) ,I opened that file in update mode
F MYFILE UF E K DISK
(i didn't mention 'A' because i dont need to append records)
now after certain checks i update (any field) with syntex.
UPDATE RECORD FORMAT
but when i run this a dump occurs like '' update without prior I/O operation."
Please tell me where i am wrong
Thanks & regards
