simple variable problem I assume

anyways, I looked through and couldnt find the answer to this specific problem I have, ok so here it is, In the mud i play we have archery, it is a two step process, first, the target must be located by direction, say MULCIBER is the target, and MULCIBER is one room north. I want to be able to setup a targetting alias, say t WHOMEVER, have it hold that target in memory as a variable of course, and then I need an alias specifically "db", and I want the alias to execute aim TARGET DIRECTION;SNIPE TARGET DIRECTION. example: db n will execute AIM presettarget NORTH;SNIPE presettarget NORTH. The target already set with the t WHOMEVER alias. So another variable needs to be assigned after db, so I can type db n, db s etc and it will respond by sending the commands in the right direction. Any help would be appreciated. thankyou.
