Delete a record from a file

Postby Bhavanijenjeti » Wed Sep 01, 2010 1:28 pm

Hi All,

I am trying to delete a record from a temporary flat file.
Can some one help me with the synatx in easytrieve to empty a temporary file or delete a specific record.

Thank You,

Like any other language using flat, ie sequential, files you read file A and write the records you want to file B.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

Once a record has been written to a sequential file, it cannot be "deleted". As suggested, you can copy the file omitting records that are not needed in the "new" file.

To create an empty file, open the file as output and do not write any records. When the file is closed, it will have no records (i.e. it will be empty).
Hope this helps,
