Use CL or HLL for lists within lists

When a command is run using CL or HLL, a list within a list is passed to the command processing program in the following format:

The number of lists is passed as a binary value of length 2. Following the number of lists, the displacement to the lists is passed (not the values that were entered in the lists). Each displacement is passed as a binary value of length 2 or length 4 depending on the value of the LISTDSPL parameter.

The following example shows a definition for a parameter KWD2 (which is a mixed list within a simple list) how the parameter can be specified by the display station user, and what is passed. The parameter definition is:

       PARM    KWD(KWD2)    TYPE(LIST) MAX(20) MIN(0) +
               DFT(*NONE)  SNGVAL(*NONE)  LISTDSPL(*INT2)
LIST:  ELEM    TYPE(*CHAR)  LEN(10) MIN(1)       /*From value*/
       ELEM    TYPE(*CHAR)  LEN(5) MIN(0)        /*To value*/

The display station user enters the KWD2 parameter as:

KWD2((A B))

The following is passed to the command processing program:

KWD2((A B) (C D))

Lists within a list are passed to the command processing program in the order n (the last one entered by the display station user) to 1 (the first one entered by the display station user). The displacements, however, are passed from 1 to n.

The following is a more complex example of lists within lists. The parameter definition is:

        PARM    KWD(PARM1)  TYPE(LIST3)  MAX(25)
LIST3:  ELEM    TYPE(LIST4)
        ELEM    TYPE(*CHAR)  LEN(3)
        ELEM    TYPE(*NAME)  LEN(2)  MAX(5)
LIST4:  ELEM    TYPE(*DEC) LEN(7 2)
        ELEM    TYPE(*TIME)
 

PARM1(((11.1  120900)  A  (A1  A2))  ((-22.2  131500)  B  (B1  B2)))
