─────NAMELIST───────────────────────────────────────────────────────────────
 
     Action
 
     Groups a set of variables together under a single name. Allows
     namelist-directed I/O.
 
     Syntax
 
     NAMELIST /namlst/ varlist [ /namlst/ varlist]
 
     Parameter          Description
 
     namlst             Name for a group of variables
 
     varlist            List of variables. May not include structure
                        variables or formal arguments.
 
     Remarks
 
     A variable name may appear in more than one namelist.
 
     If the same group name appears in more than one NAMELIST, the new
     list of variables is treated as a continuation of the previous
     list.
 
     Example
 
           INTEGER    i1*1, i2*2, i4*4, iarray(3)
           LOGICAL    11*1, l2*2, l4*4
           REAL       r4*4, r8*8
           COMPLEX    z8*8, z16*16
           CHARACTER  c1*1, c10*10
 
           NAMELIST /example/ i1, i2, i4, 11, l2, l4, r4, r8,
          +                   z8, z16, c1, c10, iarray
 
           i1  =  11
           i2  =  12
           i4  =  14
           11  = .TRUE.
           l2  = .TRUE.
           l4  = .TRUE.
           r4  =  24.0
           r8  =  28.0d0
           z8  = (38.0, 0.0)
           z16 = (316.0d0, 0.0d0)
           c1  = 'A'
           c10 = '0123456789'
           iarray(1) = 41
           iarray(2) = 42
           iarray(3) = 43 /
 
           WRITE (*, example)
 
     The following output is produced:
 
     &EXAMPLE
     I1 =           11
     I2 =           12
     I4 =           14
     L1 =  T
     L2 =  T
     L4 =  T
     R4 =        24.000000
     R8 =        28.000000000000000
     Z8 =           (38.000000, 0.000000E+00)
     Z16 =         (316.000000000000000, 0.000000000000000E+000)
     C1 = 'A'
     C10 = '0123456789'
     IARRAY =           41          42          43
 
     If a namelist-directed read is performed using READ (*, example) with
     the following input:
 
     &example
     I1=99
     L1=F
     R4=99.0
     Z8=(99.0, 0.0)
     C1='Z'
     IARRAY(1)=99
     /
 
     a second WRITE (*, example) statement produces the following output:
 
     &EXAMPLE
     I1 =           99
     I2 =           12
     I4 =           14
     L1 =  F
     L2 =  T
     L4 =  T
     R4 =        99.000000
     R8 =        28.000000000000000
     Z8 =           (99.000000, 0.000000E+00)
     Z16 =         (316.000000000000000, 0.000000000000000E+000)
     C1 = 'Z'
     C10 = '0123456789'
     IARRAY =           99          42          43
     /
