 If it were available in Gambas I would think it would be something like
Try     Date(2018,13,1)
If Error Then    Resume Next

  In VB.Net it is
Try     Date(2018,13,1)
If Error Resume Next
This will tell it to resume at the next error without taking any other action.

 I can not understand what you want to get.
Now also .net uses Try, Catch and Finally.
If you want to continue after the error set just try:
Try something
Try something else
if you want to stop set:
Try something
if error then return
Otherwise read here:
http://gambaswiki.org/wiki/comp/gb/error

In particular:
Public Sub Main()
  
  Dim x As Date
  
  Try x = Date(2018, 13, 1)
  If Error Then
    Print "Month max 12"
  Else
    Print "Exit"
    Return
  Endif
  
End

BUT IS:

Try If Date(2018,13,1) then stop
