SQLAPI oncheck question

Running IDS 11.50.FC5 on HP-UX 11.31 PA-RISC. According to the docs, if I run EXECUTE FUNCTION admin("check data", "partnum"); I should get something very similar to running 'oncheck -pt ...', and if I run EXECUTE FUNCTION task("check data", "partnum"); I should get a count of the number of rows in the table. First thing, the docs appear to have these reversed, as I get the detailed report by running task() instead of admin(). I have submitted feedback to IBM on that documentation error. Second thing, when I run admin() against a table with zero rows, I do not get 0 as a return. Similarly, if I run it against a table with 139 rows, I do not get 139 as a return. I get a number which appears to increment each time I run the command. Sometimes it increments by one, sometimes by two. Actually, if I run: EXECUTE FUNCTION admin("check data", "10487706"); EXECUTE FUNCTION task("check data", "10487706"); EXECUTE FUNCTION admin("check data", "10487706"); I get: (expression) 7448 (expression) Utilization report for dbname_dev:"owner".table Physical Address 11:1516489 Creation date 06/15/2011 12:32:57 TBLspace Flags 801 Page Locking TBLspace use 4 bit bit-maps Maximum row size 738 Number of special columns 0 Number of keys 0 Number of extents 1 Current serial value 1 Current BIGSERIAL value 1 Pagesize (k) 2 First extent size 8 Next extent size 8 Number of pages allocated 8 Number of pages used 1 Number of data pages 0 Number of rows 0 Partition partnum 10487706 Partition lockid 10487706 Extents Logical Page Physical Page Size Physical Pages 0 11:1915672 8 8 (expression) 7450 In other words, the number appears to have incremented by two because I ran the task() and the admin(). If I run task(), followed by another iteration of task(), the number increments by one. What is this number? Is it merely a sequential counter of how many times task() and/or admin() have been executed? It doesn't seem to be related to the specific partnum, as I tried running the task() with one partnum and the admin() with another, and yet when the second task() ran, it still reported a number two larger than the first task(). Is there any way to get a return code for success/fail? I'd like to automate this and only set an alert if the 'check partition' reports a problem.
