Re: Create a member in a given file?

[magne@xxxxxxxxx]

Hi Thorbjørn,
I am not sure why you are using IFS classes when you are working with iSeries 
database files, but maybe I am outdated on this.
See the enclosed keyed file example and sequential file access java program 
from jt400.
If you need to create a member in a file, you could use the command call:
CommandCall c = new CommandCall(system, "ADDPFM FILE(library/filename) 
MBR(membername)");
Best regards,
Magne
