Return a val from a function

[alhassani54]

my script
#!/bin/ksh
#
function f_a
{
flag=1
}

function f_b
{
integer flag=0
f_a
if [[ $flag = 1 ]]; then
echo "flag=1"
fi
}
.
.
.
from function f_a I would like to return the value of flag equal 1 to function f_b.

Any help will be appreciated.

Thanks

Kais

export flag

I exported flag inside the function f_b and outside but it did not work.
