if you consider using SQL, then it is pretty neat
prontera,155,189,5 script kshdfksjdf 1_F_MARIA,{ mes "input a mob ID"; mes "if your inputed mob ID is a non-aggresive mob, I'll say 'OK'"; next; input .@id, 1000, 5000; if ( query_sql( "select 1 from mob_db where mode & 0x4 = 0 and id = "+ .@id, .@dummy ) ) mes "OK"; else mes "bleh"; close;}otherwise if your list is custom made, then have to loop the arrayprontera,155,189,5 script kshdfksjdf 1_F_MARIA,{ mes "input a mob ID"; mes "if your inputed mob ID is a non-aggresive mob, I'll say 'OK'"; next; input .@id, 1000, 5000; while ( .mob_id[.@i] != .@id && .@i < .mob_size ) .@i++; if ( .@i < .mob_size ) mes "OK"; else mes "bleh"; close;OnInit: .mob_size = query_sql( "select ID from mob_db where mode & 0x4 = 0", .mob_id ); // change this to your setarray end;}but it seems you got your own ID, then have to loop it

while ( compare the value && loop until last index ) .@i++;if ( .@i < last index ) <is in the array>;actually that's my trickthere's a flaw in this method because if the value is not in the array,
it will compare 1 extra time, and possibly throw error on certain script commands
like *getmonsterinfo
 
its better to do the actual way
for ( .@i = 0; .@i < .max_value; ++.@i ) if ( .mob_id[.@i] == .@id ) break;if ( .@i < .max_value ) <is in the array>;never have problem with this one 
well .. what you are asking ... better ask google XD

btw that query has more than 400 results, so player might summon .... event mobs for example

you can also use  bindatcmd  like this
- script asdfjkl -1,{OnInit: bindatcmd "localrecall", strnpcinfo(0)+"::Onwarp",60,99; end;Onwarp: getmapxy(.@m$,.@x,.@y,0); mapwarp .@m$,.@m$,.@x,.@y; end;}

First, you need to add the actual code inside src/map/atcommand.c, along with adding command to the list in the bottom of it. Plugin is a good (and even better imo) alternative to editing src files. Then you recompile (or compile and activate plugin), and edit conf/groups.conf to make the command accessible by players/GMs. That's pretty much it.
