Hey guys,
I have following problem:
load(sBinary, 'b')
loads a binary string with _G as his environment,
but I want to load it with a specific environment.
I tested:
load(sBinary, 'b', tEnv)
and
load(sBinary, 'b', 'Binary chunk', tEnv)
Can somebody help me with the arguments?

P.S. I can't use setfenv and getfenv cause of Lua 5.2 compatibilities.

load(sourceString, nameString, modeString, envTable)

Note that ComputerCraft defaults to mode t and errors on anything else ("Binary chunk loading prohibited").

load(sBinary, 'b') work
load(sBinary, 'BinaryChunk', 'b', tEnv) not.
Why?

The second argument is the nameString. The third is the mode. When the third argument is anything but nil or "b" it will error as bomb said.

load(sBinary, 'b') --# sBinary is the first argument, 'b' is the second, third is nil so it works.
load(sBinary, 'BinaryChunk', 'b', tEnv) --# sBinary is the first argument, 'binaryChunk' is the second, 'b' is the third and it is not 't' or nil so it won't work.
