Re: Processing Command Parms

Concerning the "Offset to entry in the list (in reverse order)" comment, my
recollection is that the list entries are received in the entered order and
it's just that the storage offsets to the list are in reverse order (that
is, load from the back of the parameter). While using descending storage
offsets/addresses is not ideal from a paging point of view, this should be
transparent to the CPP processing.

Jon,

Beware: Top of my head.

List in lists:

A) 5i0 Number of entries in parameter list
B) 510 Offset to entry in the list (in reverse order); this occurs
many entries are in the list (if max=10, and 3 are entered, this is
repeated 3 times)
C) after that the parameter values in their lay out of an element DS

Ex parm (Max 10 entries) length 15, 2 elements (10-5) (Spaces between
segments for clarity)

A B C

Thank you so much Gary - it is neither easy to find nor easy to
understand but at least I have a starting point now. The only docs I had
found gave examples of only the simple stuff and it is mixed lists and
lists in lists that I have to deal with - thanks again.

IBM doesn't make it easy that's for sure. The best I ever found was in

the CL programming guide. There is a section entitled " Defining lists for
parameters"

http://www-01.ibm.com/support/knowledgecenter/ssw_i5_54/
rbam6/dflst.htm

Under each list type there is a section entitled "Using CL and HLLs for"
the type of list. Each section breaks down how the list is structured.

For example, a simple list is passed as |number of values
passed|value1|value2|...|valuen

Subject: Processing Command Parms

I cannot for the life of me find a simple explanation of how command
parms are passed to the CPP. Apparently I've never had to handle variable
length lists of things like qualified names when I've dealt with commands
in the past. Either that or it was so many years ago I have forgotten.

Anyone point me to useful IBM docs? The stuff I've found so far in the
Info Center is not that helpful.
