Newbie: Problem with irb

ruby-talk
1

C:\RUBY\BIN\RUBY.EXE No such file or directory -- irb (LoadError)
C:\RUBY\BIN\RUBY.EXE No such file or directory -- erb (LoadError)
C:\RUBY\BIN\RUBY.EXE No such file or directory -- rdoc (LoadError)

Check the header for C:\RUBY\BIN\IRB.BAT (or erb or rdoc .bat files).
Should look like:

@echo off
"C:\ruby\bin\ruby.exe" "C:\ruby\bin\irb" %1 %2 %3 %4 %5 %6 %7 %8 %9

Check the header for C:\RUBY\BIN\IRB.BAT (or erb or rdoc .bat files).
Should look like:

@echo off
"C:\ruby\bin\ruby.exe" "C:\ruby\bin\irb" %1 %2 %3 %4 %5 %6 %7 %8 %9

the actual top lines are

ruby -Sx "%0" %1 %2 %3 %4 %5 %6 %7 %8 %9

for win9x, and

ruby -Sx "%~nx0" %*

for win nt, then some codes at the bottom. I don't understand what
"%0" or "%~nx0" actualy do. Care to explain? As for
"C:\ruby\bin\ruby.exe" from your snippet, I think the OS should find
it cause it's in the search path without specifying the absolute path.

TIA
