  
      The  VAX  command  "FLECS" reads a file 'file.FLE' containing FLECS
 code and generates the equivalent FORTRAN in 'file.FOR' and an  indented
 listing in  file  'file.LIS'.  The valid command options are -FORMAT and
 -HELP. 
  
 FLECS allows the following control constructs: 
  
     REPEAT UNTIL (cond) stmt               UNTIL (cond) stmt
  
     REPEAT WHILE (cond) stmt               WHILE (cond) stmt
  
     SELECT (expression)                    CONDITIONAL
     .  (expr1) stmt1                       .  (cond1) stmt1
     .  (expr2) stmt2                       .  (cond2) stmt2
     .  ...                                 .  ...
     .  (OTHERWISE) stmt                    .  (OTHERWISE) stmt
     ...FIN                                 ...FIN
  
     IF (cond) stmt                         DO (loop expr) stmt
  
     UNLESS (cond) stmt                     Perform-Function
                                            TO Perform-Function
     WHEN (cond) stmt1                      .  stmt
     ELSE stmt2                             ...FIN
  
 Each statement should be entered in column 7 of a line, as FLECS indents
 from column 7.  FLECS keywords must be in upper case. 
  
      The current FLECS Preprocessor is Version 22.54 from the University
 of Oregon, with some additional changes: 
  
    - The message "(FLECS VERSION 22.54)" is omitted from listings.
    - Statement sequence numbers are omitted from the generated FORTRAN.
    - FLECS errors are indicated as a VAX warning-level abort.
