I am talking about calling the script with the full path of the script interpreter, which contains a space: X:\>"\\vbitmuis\tldev\Mas ter\bin\win32\texlua" x:\epspdf\lua\tlu_call\tlu_caller_rk.tlu Output from the patched version: PATH[1]: C:\WINDOWS\system32 PATH[2]: C:\WINDOWS PATH[3]: C:\WINDOWS\System32\Wbem prepending "//vbitmuis/tldev/Mas ter/bin/win32" (os.selfdir) to PATH PATH[1]: C:\WINDOWS\system32 PATH[2]: C:\WINDOWS PATH[3]: C:\WINDOWS\System32\Wbem Note that under TL/w32 os.getenv returns the parent path. Maybe this should be considered a bug, although the modified path is visible to child processes. For completeness: this is the output with portable miktex: X:\>"x:\mik port\miktex\bin\texlua" x:\epspdf\lua\tlu_call\tlu_caller_rk.t 1. os.execute 'x:\mik' is not recognized as an internal or external command, operable program or batch file. ... PATH[1]: C:\WINDOWS\system32 PATH[2]: C:\WINDOWS PATH[3]: C:\WINDOWS\System32\Wbem prepending "x:\mik port\miktex\bin" (os.selfdir) to PATH PATH[1]: x:\mik port\miktex\bin PATH[2]: C:\WINDOWS\system32 PATH[3]: C:\WINDOWS PATH[4]: C:\WINDOWS\System32\Wbem Under MikTeX, os.getenv does return the modified path. -- Siep Kroonenberg
