Open a mainframe file in append mode in clist
Can any one please help me to open a mainframe file in clist in append mode?  I know to open a file in output mode we do the following.  First we allocate a new file  ALLOC DA(‘&PS’) F(OUTFIL) NEW SPACE(20 20) TRACKS RELEASE + LRECL(80) RECFM(F B) DSORG(PS) and then we open it using the following  OPENFILE OUTFIL OUTPUT Â
I want to open the file such that it can be modified each time its open and does not overwrite what is already written in the file
