    \$\begingroup\$ On my Windows VM, Winload.exe is sufficient... \$\endgroup\$ Commented Apr 1, 2016 at 23:07
  • \$\begingroup\$ I think it has to be a number because if it is a letter then it would be treated as a variable, to treat it as a string quotes are required, and they waste bytes. :P \$\endgroup\$ Commented Apr 2, 2016 at 15:14

    \$\begingroup\$ @QPaysTaxes MathuSum has it correct. The second 1 needs to be a number of some sort in order for the implicit parsing to work correctly. Anything from [0-9] would work the same. \$\endgroup\$ Commented Apr 4, 2016 at 12:17

    \$\begingroup\$ @Nacht Maybe it's a quirk of my particular environment, then. In my ISE (PSv4 Win8.1), replacing the second 1 with anything non-numeric (and not specified either as .\a or a.txt or the like) results in a parse error. \$\endgroup\$ Commented Apr 5, 2016 at 12:21
