Re: %lookup on qualified DS array

James,

Finally got back to this and, as written your method didn't quite
work. (what, you're not going to test this stuff for me? ;-) But
thanks again for getting me off the bad track and on to the path of
lookuppy goodness.

For the record and the archives, this is how I ended up doing it:

D l$ ds
D l$a
D lookVers like(VERSION) overlay(l$a)
D lookFile like(FILE) overlay(l$a : *next)

D c$a s like(l$a) dim(9999) inz

lookVers = S1VERSION;
lookFile = S1FILE;

if %lookup(l$a:c$a) > 0;
...duplicate error...
else;
$idx += 1;
c$a($idx) = l$a;

You can't use %lookup() on a data structure. If I need to use a data
structure with look up capabilities I usually create an array element
and overlay the element.

Example:
d c$              ds                  qualified inz
d array                               dim(9999)
d  cpyVers                            like(VERSION) overlay(array)
d  cpyFile                            like(FILE) overlay(array : *next)

Then you can do something like this.
i = %lookup(lookVers : c$.cpyVers);
if (i > 0);
 foundVers = c$.cpyVers(i);
endif;

Something like that should work.

Hey all,

I'm trying to use a data structure to lookup a dimmed datastructure
array, as follows:

d l$              ds
d  lookVers                           like(VERSION)
d  lookFile                           like(FILE)

d c$              ds                  qualified dim(9999) inz
d  cpyVers                            like(VERSION)
d  cpyFile                            like(FILE)

If %lookup(l$:c$) > 0;

RNF0571 20      1 The second parameter for %LOOKUPxx is not valid.

I also tried:

D l$              ds
D  lookVers                           like(VERSION)
D  lookFile                           like(FILE)

D c$              ds                  likeds(l$) dim(9999) inz

same error.   what good is dimming a data structure if you cant do a
lookup on it?

Thanks!
