  Purpose
 
  Synopsis
 
function ishidden(c:nlctr):boolean
 
  Argument
 
| 
     c 
     | 
     A nonlinear constraint
     | 
  Return value
 
 true if the constraint is hidden,
 false otherwise.
  Example
 
 The following tests whether a nonlinear constraint is hidden.
 
uses "mmnl"
declarations
 c: nlctr
end-declarations
if ishidden(c) then
 writeln("Constraint 'c' is currently hidden.")
end-if
  Further information
 
 This function tests the current status of a constraint. At its creation a constraint is added to the current problem, but using the function
 sethidden it may be hidden. This means, the constraint will not be contained in the problem that is solved by the nonlinear solver but it is not deleted from the definition of the problem in Mosel.
