Parameter 4 is wrong too.  If you define your error code parameter as *
CONST, you will encounter many and varied problems (even if it
apparently works sometimes).  Here's one way to define the error code
parameter:

    D ErrCode         DS
    D   ByteProv                    10I 0 Inz(0)
    D   ByteAvail                   10I 0 

    D ChgUS           PR                  ExtPgm('QUSCUSAT')
    D  SpaceLib                     10A   Const
    :
    :
    D  SpaceError                         LikeDs(ErrCode)

Then pass ErrCode as the parameter.  If you want to check for errors
after the call, initialize ByteProv to %Size(ErrCode) instead of zero.
