Trying to write multiple lines to a pds member using todsn. The second attempt fails with the -a option. If i remove the -a it works, but overwrites the first line.
error:
+ printf -- '-NOTE: %s%s%s\n' 'Failed to read ORDERID' 0i3fx jostest-bsa
+ todsn -a '//OSP.BSADV.HJ01234.HJ56799(REQSTAT)'

I was able to append to a flat file. Would like to use a pds member if posssible.

Co:Z uses the IBM C library for file and dataset I/O. It is not possible to append to a PDS member. This is similar to the restriction in JCL that it is not possible to write to a PDS member using DISP=MOD.
