st: problem with "byable(recall)"

[Sophie Roidot et Pierre Gaudebout <roidot.gaudebout@free.fr>]

--
I have some problems in the use of " byable ( recall ) ".
I am responsible for the statistical analysis of an survey of 
satisfaction of the patients hospitalized in several Parisian 
hospitals (26 hospitals with hundred of questionnaires realized by 
hospital with drawn lots outgoing patients).
The questionnaire includes 43 items of satisfaction.
Every item containing 5 modalities of answer (from " very satisfied " 
(5) to " In no way satisfied " (1)).
One of my objectives is to compare for every item the % of very 
satisfied persons in a hospital to that of 25 other hospitals.
I realized a program allowing the comparison from a hospital to 25 
others and I would like I could make this program run with the option 
" by " hospital " ". I know that I have to use " byable ( recall ) 
but my attempts failed.
Somebody could put me on the way.
( At the moment the only solution which I found to by-pass this 
problem is to use one " forvalues k = 1 ( 1 ) 26 {" myprog " `k '})
My program is the following one:

capture log close
log using boucles3, replace
set more off

# delimit ;
*program drop test_item;

program define test_item/*, rclass sortpreserve byable(recall)*/;
