luac does not give me output

.../Program Files/LUAC/5.1/ contain the downloads of luac from lua-5.1.5_Win64_bin files and luac.out

I want to get the bytecode listing from: "C:/ProgramData/Calico Pie/Family Historian/Plugins/!!XPcall.fh_lua"

and output it to : "C:/ProgramData/Calico Pie/Family Historian/Plugins/IRP/5.1//!!XPcall.irp" *****file may or may not exist the direcory structure does.

it is not occurring

in every case _err = ''

-- output file not created, _err = ''

_IRP= "C:/Program Files/LUAC/5.1/luac5.1.exe" -l -o "C:/ProgramData/Calico Pie/Family Historian/Plugins/!!XPcall.fh_lua" "C:/ProgramData/Calico Pie/Family Historian/Plugins/IRP/5.1//!!XPcall.irp"

-- output file not created, _err = ''

_IRP= "C:/Program Files/LUAC/5.1/luac5.1.exe" -l "C:/ProgramData/Calico Pie/Family Historian/Plugins/!!XPcall.fh_lua" -o "C:/ProgramData/Calico Pie/Family Historian/Plugins/IRP/5.1//!!XPcall.irp"

-- output file not created, _err = ''

_IRP= "C:/Program Files/LUAC/5.1/luac5.1.exe" -l "C:/ProgramData/Calico Pie/Family Historian/Plugins/!!XPcall.fh_lua" > "C:/ProgramData/Calico Pie/Family Historian/Plugins/IRP/5.1//!!XPcall.irp"

--output file not created, err = '' !!XPcall.fh_lua trashed

_IRP= "C:/Program Files/LUAC/5.1/luac5.1.exe" -l > "C:/ProgramData/Calico Pie/Family Historian/Plugins/!!XPcall.fh_lua" "C:/ProgramData/Calico Pie/Family Historian/Plugins/IRP/5.1//!!XPcall.irp"

local handle = io.popen(_IRP)

err = handle:read('*a')

handle:flush()

handle:close()

I also intend to compile objects from various Plugins subfolders and install the compiled object in the Plugin folder itself:

_OBJ = "C:/Program Files/LUAC/5.1/luac5.1.exe" -t -s -o "C:/ProgramData/Calico Pie/Family Historian/Plugins/QSYS_HDR.lua" "C:/ProgramData/Calico Pie/Family Historian/Plugins/QSRC/QSYS_HDR.lua"

where the source file is intended to be : "C:/ProgramData/Calico Pie/Family Historian/Plugins/QSRC/QSYS_HDR.lua"

and the compiled object is intended to be: "C:/ProgramData/Calico Pie/Family Historian/Plugins/QSYS_HDR.lua"
