The current standard of Simula DOES have a text concatenation operation. This
operator always creates a new text object and does not change any of the
operands. Both constants and variables can be handled by the operator.
Example:
   begin
      text x = "Foo";   ! --- Declaration of text constant ---;
      sysout.outtext(x & "f" & "a" & "h!");
   end;
This program yields "Foofah!" on the standard output.

The current standard of Simula is published as a Swedish national standard
document: SS 636114 (ISBN 91-7162-234-9). It is available via all other national
standardization bodies. (And via Simula vendors.)
