Description davidmo 1999-06-24 03:48:10 UTC 
Shell variables seem to exhibit local scoping behavior.
Example:
#!/bin/sh
i=0
cnt=0
while [ i -lt 5 ]
do
   cnt=$cnt+1
   echo $cnt
   i=$i+1
done
echo $cnt

results:
1
2

This issue has been forwarded to a developer for further action.
Comment 2 Cristian Gafton 1999-07-02 21:45:59 UTC 
The example provided is invalid (is not a shell script)
