Re: WEIRDNESS in list parameter in CL program:

Rob is correct. That structure is one (of many possible) CPP definition for
the list parameter. And while I'm not sure which article that came from, I
(in general) wouldn't use it of late. I would instead use a pointer based
approach to handle the list entries (much more flexible).

Dean,

I 'think' that the list parameter will GENERATE such an item.
Dcl Var(&ListParm) Type(*Char) Len(162)
Dcl Var(&NbrEnt) Type(*UInt) Len(2) +
Stg(*Defined) DefVar(&ListParm 1)
Dcl Var(&UserLst) Type(*Char) Len(160) +
Stg(*Defined) DefVar(&ListParm 3)

I don't think it will CONSUME such an item.

IOW, if you front end your program with a command that has a list
parameter you may need the logic of the data structure above to process
that parameter. But methinks you cannot pass such a parameter to the
command.

This program blows up


&LISTPARM *CHAR 162 ' A123456789 B234567890
C' 0004C1F1F2F3F4F5F6F7F8F940C2F2F3F4F5F6F7F8F9F040
+26 '1 D23 '
F140C4F2F340404040404040404040404040404040404040
&NBRENT *UINT 2 4 0004
&USERLIST *CHAR 160 'A123456789 B234567890

+26 'D23 '
C4F2F3404040404040404040404040404040404040404040


DCL &ListParm *char 162
DCL &NbrEnt *uint 2 stg(*defined) DefVar(&ListParm 1)
DCL &UserList *char 160 stg(*defined) DefVar(&ListParm 3)
chgvar &UserList 'A123456789 B234567890 C1 D23'
?GRTOBJAUT OBJ(A) OBJTYPE(*FILE) USER(&UserList) /* Fails */

chgvar &NbrEnt 4
?GRTOBJAUT OBJ(A) OBJTYPE(*FILE) USER(&ListParm) /* Also fails */

James,

The reason your approach won't work is because a list parameter as the
number of entries in the list as a 2 byte integer at the beginning of the
variable. So, for your situation you could try something like this:

Dcl Var(&ListParm) Type(*Char) Len(162)
Dcl Var(&NbrEnt) Type(*UInt) Len(2) +
Stg(*Defined) DefVar(&ListParm 1)
Dcl Var(&UserLst) Type(*Char) Len(160) +
Stg(*Defined) DefVar(&ListParm 3)

I know I've done something like this in the past, but I can't find my
exact example right now. I pulled this definition from an article by
Bruce Vining on www.mcpressonline.com.

If I format the variable I'm passing as CHAR(175) passing up to 16 user
profiles, space-delimited (the way I would enter it on a command line,
e.g., "FOO BAR BAZ ABCDEFGHIJ CORGE"), then it rejects it, taking "FOO
BAR BA" as a single list entry.

If I format the variable I'm passing as CHAR(160) passing up to 16 user
profiles aligned on 10-byte boundaries, it STILL rejects it.

What does it want?!?

HELLLLLPPPPPP MEEEEEEEEEEEE!
