I`ve an problem:
In this program:
`--------------------------------
`dimtest by PaPi 16-04-2014
dim i as integer
dim j as integer
i=10
j=20
sub testsub(jj as integer)
dim i as integer
i=jj+jj
showmessage str$(i)
end sub
testsub(j)
showmessage "end"+str(i)
`-----------------------------
The fnxcompiler say :
error 1 line 8 Variable `i` already exists.
Try this, Marco!
But, I know that the outside and inside written
" dim i as integer "
instructions independent of each other. Is not that right?

They are independed if you usedthem not already, a global dimmed var in the root of the program overrules the ones in the subs.
To keep the global var global you can not use it in the subs.
if you have this posibility
dim i as integer
i=10
sub test(i as intger)
i=20
print i `` no acces to global that`s why it is blocked by an already exists error
end sub
best regards

Thank you very mutch.
In short, can not use the same name for a global variable and a local variable at the same time. So this is a FNXBASIC features, as it is usually not the case (in other languages[ch8203][ch8203]).
