-diagfile     filename | stderr | stdout

All non-error messages and output will be written to this file (default is stderr).

-errmsgpre     tag

-errfile     filename | stderr | stdout

All error messages will be written to this file (default is stderr).

-noshell

The -noshell command line option is intended to disallow any shell commands that a user might supply in a script from being executed. The following script constructs are disabled when -noshell is in effect:

 #proc getdata
   command:   myshellcommand
 
 #proc getdata
   file:    filename  (because this allows shell expansion of wild cards)
   (use "pathname" instead)
 
 #shell
     myshellcommand
 #endshell
