! Abstract:
!   This file contains the language constructs that make up the 
!   structure definitions for Flow and NS diagrams.
!
! Author:
!   C.M. Lindhout
!
! Creation Date:  28-8-1989
!
! Modification History:
!   5-12-1989 Marion van Geest:
!
!   Structure removed from this file and inserted with standard environments
!   in Latex_environments.lse
!   Some file layout formatting and comment changes
!
! Known bugs:
!
!	\LABEL command definition for flow supersedes the standard LaTeX 
!       \label command definition. May cause some syntactic errors
