ZMA CTLR EXPERIENCED OPERROR AT FL190; WHEN VECTORING TO AVOID MOA; AN INCORRECT ALT WAS ISSUED CONFLICTING WITH ANOTHER ACFT.

Narrative

I WAS WORKING A SECTOR WHERE THERE WAS AN ACTIVE MIL MOA. THE DEPS FROM ORLANDO APCH AIRSPACE WERE ON HDGS THAT AIMED THEM RIGHT AT THE ACTIVE MOA. I WAS GIVEN 2 DEPS SIDE BY SIDE OUT THE DEP TRANSITION AREA THAT I NEEDED TO CLB ABOVE ORLANDO APCH'S AIRSPACE SO THAT I COULD TURN THEM TO KEEP THEM CLR OF THE ACTIVE MOA. I CLBED THE ASTROJET TO FL190. WHEN THE ASTROJET WAS OUT OF FL180 I TURNED HIM TO A HDG TO KEEP THE ACFT CLR OF THE ACTIVE MOA AND I CLBED THE BOEING TO 17000 FT. WHEN THE BOEING WAS AT 17000 FT; I TURNED HIM TO KEEP THE ACFT CLR OF THE ACTIVE MOA. WHEN THE ASTROJET WAS AT FL190; I THOUGHT I CLBED THE BOEING TO FL180 BELOW THE ASTROJET. I PUT FL180 INTO THE BOEING'S DATA BLOCK. AS I BEGAN TO ISSUE THE TFC TO THE BOEING; I SAW HIM CLB THROUGH FL180 AND I RECLRED HIM TO MAINTAIN FL180. HE SAID THAT HE HAD BEEN ASSIGNED FL190; BUT WAS DSNDING BACK DOWN TO FL180. WHEN LATERAL SEPARATION HAD BEEN ESTABLISHED BTWN THE BOEING AND THE ASTROJET; I CLBED THE BOEING TO FL230 AND HANDED HIM OFF TO THE NEXT SECTOR. UPON LISTENING TO THE TAPES; I FOUND THAT I HAD CLBED THE BOEING TO FL190; NOT THE FL180 THAT I HAD INTENDED AND HAD PUT INTO THE DATA BLOCK. THE ACFT WERE 3 MI AND 500 FT APART. THE PROC FOR AIMING DEPS AT AN ACTIVE MIL MOA ARE STANDARD FOR THIS SECTOR. ON SEVERAL OCCASIONS OVER THE PREVIOUS WKS; I HAD EXPRESSED MY CONCERNS REGARDING THIS UNSAFE PROC. I EVEN OFFERED SEVERAL SUGGESTIONS FOR IMPLEMENTING SAFE PROCS THAT WOULD KEEP THE DEPS AWAY FROM THE MOA. I DO NOT KNOW OF ANYWHERE ELSE IN THE COUNTRY WHERE ACFT ARE AIMED AT AN ACTIVE MOA AND THE CTLR IS THEN GIVEN A VERY LIMITED AMOUNT OF TIME AND DISTANCE TO TURN THE ACFT OUT OF HARM'S WAY.
