prunsrv does not read numeric or multiple parameter arguments from the
environment properly.
e.g.
set PR_STOPPARAMS=stop
set PR_STOPTIMEOUT=20
prunsrv //IS//XXX
will result in the service XXX having neither value set, only ordinary string
parameters work e.g. set PR_STDERROR=auto
Such parameters can be set on the command line as a workaround.
add code to read numeric variables and correct code which reads multiple string
variables
