The question itself shows the problem. You aren't "losing" anything.
You are operating in a different namespace, and that new namespace
doesn't know what 'dabo' is until you tell it.
Since we're using VFP analogies, think of local variables: when you
call another method, that new method doesn't know anything about any
locals declared in the calling procedure. You didn't "lose" those
variables; the new procedure has its own local variable 'namespace'.
So if the calling procedure has:
LOCAL lcName
lcName = "John"
myfunc()
? "TOP LEVEL", lcName
FUNCTION myfunc
* This will throw an error
? lcName
LOCAL lcName
lcName = "Ed"
? "MYFUNC", lcName
RETURN
Notice how 'lcName', even though defined in the calling procedure,
is not available in the function until you create it. Then, when
control returns to the main program, the original 'lcName' is still
intact; changing a variable in the function that happened to have the
same name didn't affect it, since those variable names were in
different namespaces. You could think of them as actually being named
'toplevel.lcName' and 'myfunc.lcName', clearly showing that they are
not the same thing.
Hope this helps,
