1. reading errorlevel value...
Hi all!
Is there anyone to know how to get the errorlevel value returned by
a program which is excuted by the "system()" command of Euphoria?
Thanks much in advance!

Hey, for once I know an answer! I remember this from reading the old
logs and here it is:
Unless Robert Craig has changed something since then, the Watcom routine
Euphoria calls (when you call system() ) does not provide any meaningful
return value.
Or, nope, can't do it.
Of course, somebody may have figured out how to get around that by now .

MS-DOS has a couple of variables that any program can access call
environment variables
You can access them (from library.doc) like this:
------------------------------------<getenv>----------------------------------
Syntax: x = getenv(s)
Description: Return the value of a DOS environment variable. If the
variable
is undefined return -1.
Example: e = getenv("EUDIR")
-- e will be "C:\EUPHORIA" -- or perhaps D:, E: etc.
Comments: Because either a sequence or an atom (-1) might be
returned, you
should probably assign the result to a variable declared
as
object.
See Also: command_line
------------------------------------<end of
getenv>---------------------------
The variable you want to call is 'ERRORLEVEL'
So to acces the errorlevel returned by an application do something like:
e = getenv("ERRORLEVEL")
And e will hold the ascII representation of the errorlevel value. (I
think)
I'm am not 100% sure about this, but in a batch file (.bat) you use the
same method to acces the errorlevel as you use with any other
environment variable.
