Hi, all,
Doing some playing with Lua 5.2's goto for branching a script
depending on the string variable returned by an application API
method, in my test case, a method returning the name of the host
operating system. But thus far, I have been unable to persuade goto to
accept a string variable as the target label. I get a missing name
error for the variable label's name. Is this a known limitation or is
there some way to write something like:
s=var
goto s
::var1::
...
goto Exit
::var2::
...
goto Exit
[etc.]
::Exit::
? If so, I would appreciate a pointer on the correct syntax for the
first goto line.
Paul
