Pre-Processor Question

Hi All,

I want to build a for each loop that let's the user choose the field order of the break by statement. How can I do this? I thought about using the pre-processor to do it but can't get it to work...

if choice = "Product Line" then do:
&scoped-define str pt_prod_line
end.
else do:
&scoped-define str pt_part
end.

for each pt_mstr no-lock by {&str} :
display {&str} .
end.

This won't work because str will always end up being defined as pt_part (obviously), but it gives you an idea of what I am trying to do.

Thanks,
Rob
 
yeah - i have read on other posts that v9 has dynamic queries that let you do that, but i am running v8.3 with no chance of upgrading to v9 for quite some time... is there any way to do this without using dynamic queries?

Um .. maybe .. call a different ".p" or internal procedure one with the first query and the second with the other

eg.

if type = 1 then run a.p else run b.p

maybe return a temp-table?? I'd say upgrade to v9.

You should forget about doing dynamic query with progress 8.3b...it's really too much effort !!
 
try this one w/ include file:

if choice = "Product Line" then do:
{a.i &str pt_prod_line}
end.
else do:
{a.i &str pt_part}
end.


/*program: a.i */
for each pt_mstr no-lock by {&str} :
display {&str} .
end.
 
oops sorry i forgot to put "=" sign.

try this one w/ include file:

if choice = "Product Line" then do:
{a.i &str="pt_prod_line"}
end.
else do:
{a.i &str="pt_part"}
end.


/*program: a.i */
for each pt_mstr no-lock by {&str} :
display {&str} .
end.
