For synchronous processing,
the CONNECTSTATUS system option specifies whether the Transfer Status
window is displayed during a PROC UPLOAD or a PROC DOWNLOAD. This
system option can be overridden by specifying the CONNECTSTATUS= option
in subsequent PROC UPLOAD, PROC DOWNLOAD, RSUBMIT, and SIGNON statements.
For asynchronous processing
(NOCONNECTWAIT), the CONNECTSTATUS system option and the CONNECTSTATUS=
option in a SIGNON statement are ignored. To enable the Transfer Status
window for asynchronous processing, you must specify CONNECTSTATUS=YES
in the PROC UPLOAD, PROC DOWNLOAD, or RSUBMIT statement.
