function Msg(param)

     reaper.ShowConsoleMsg(tostring(param).."\n")

end

• Set Msg console output function

function table.maxn( table )

• Define a function to find the maximum value of an array

local maxn, k = 0, nil

• Define variables for storing maximum value and array value.

repeat

k = next( table, k )

if type( k ) == 'number' and k > maxn then

maxn = k

end

until not k

• Get index value from array. If the obtained value can be converted into a numerical value and is larger than the provisional maximum value, the obtained value is set as the provisional maximum value. Repeat this process from the beginning to the end of the array.

return maxn

• Returns the provisional maximum value as the final maximum value.

a = {"a","b","c"}

x = table.maxn(a)
