A little playing around and I've noticed that if I have an acl_variable
with an value (say a simple short integer of '4') if I run a conditional
set command preserving the original value requires a bit of thought.
This will set the value of $acl_m_userouter to 2, if it's currently '1'
else set it to empty (overwriting any value it already had)
set acl_m_userouter = ${if == {$acl_m_userouter}{1}{2}}
This will set the value of $acl_m_userouter to 2, if it's currently '1'
else preserve current value:
set acl_m_oldrouter = $acl_m_userouter
set acl_m_userouter = ${if ==
{$acl_m_userouter}{1}{3}{$acl_m_oldrouter}}
This will set the value of $acl_m_userouter to 2, if it's currently '1'
else preserve current value:
set acl_m_userouter = ${if ==
{$acl_m_userouter}{1}{2}{$acl_m_userouter}}
But is there a more simple way to say 'if this variable has the value of
1, set it to 2 - otherwise leave the existing value.
The methods above work, but I'm wondering if there is a
shortcut/placeholder for the current value of the variable?
