echo "Processing the following command line arguments: ${*:-none}"
echo "Script:    for loop outside a function:\t\c"
for Var

Function3 -eq -ne -gt -ge -le -lt
Function4 -eq -ne -gt -ge -le -lt '-ge 1 -a 2 -ge'

# Now the same call like Function4 but with Function1
Function1 -eq -ne -gt -ge -le -lt '-ge 1 -a 2 -ge'
