solveropts not working

[JeremyButcheck]

Hi I'm having trouble with the solveropts argument "pfilter" and "filter" with sparc 2.48 and DLV Dec 17 2012. Somehow the argument is not being passed from sparc to DLV. In the screenshot I compile using sparc and pass the compiled file and desired filter to DLV and it gives the expected output. Thanks.

Thank you for reporting this issue.
Indeed, command-line -pfilter is broken.
In the latest SPARC, I rename most of the predicates in the DLV program, so using -pfilter from command line no longer has the desired effect.

Please use "display" section to show only "holds" predicates.
To do so, please extend the file s_blocks3.sp with the following two lines:

display
holds.

Please see section 4.5 of the manual for the details.

Thank you.

Here is an example of using display section:

sorts
#fluent = {f1, f2}.
#action = {a1,a2}.
#time = 1..5.
predicates
holds(#fluent, #time).
occurs(#action, #time).
rules
holds(f1,1).
occurs(a1,2).

display

holds.

The displayed answer sets will only include "holds(f1,1).".

Gotcha. Thanks for your help.
