PQR Taints slash commands. Any alternatives?

[G0tha]

Hey, i am looking for alternatives to make my manual mode working. The expansion is cataclysm, should i stick to slash commands in macros or move to CVars or do you know any other alternative that actually could work?

if GetMacroInfo("PS") ~= "PS" then 
CreateMacro("PS", "INV_MISC_QUESTIONMARK","#showtooltip Psychic Scream\\\n/PS", 1, nil) 
print("Created Psychic Scream macro!")
end

if UsePsychicScream == nil then UsePsychicScream = 0 end
SLASH_PS1 = '/PS'

function SlashCmdList.PS(msg, editbox)
UsePsychicScream = GetTime()
end

if UsePsychicScream > GetTime() - 1 
then return true
end
