Use online and update/delete the records of a file

Hi,

Please let me know is there any possibility of deleting some records from a PS file(based on some conditions) via online screens.

if you are talking about qsam, even if you could access the file from CICS (i assume that's what you mean by 'online') the only way to delete (or add) records to a qsam file is by creating an second file based on the first and the adds/deletes you want to make.
this is called Father-Son processing.

you can not do direct deletes to a qsam file.

now if you are talking about esds, then yes you can. refer to the cics manuals for info.

qsam files are not allocatable by cics (other than as a tdq, but then you still have the Father-son requirement).

esds vsam files are allocatable by cics. there are api's to perform i/o on vsam files, there are no api's to perform i/o on qsam files.
