  API for Interactive Login Limit? 
 The Question is:
 
I can list the interactive logins limit and current value with the command SET
 LOGINS /INTERACTIVE but is there a system call I can make to get those values?
 
 The Answer is :
 
  See SYI$_IJOBLIM, via the sys$getsyi[w] system service.
  Also see IJOBLIM via the f$getsyi DCL lexical function.
  The current count can be obtained with a wildcard $getjpi.
