In 7.x config commands are written with a forward slash to separate the tree structure.
Example
/ip/firewall/nat
But in export this is gone???
/ip/firewall/nat> export
# sep/15/2022 22:09:58 by RouterOS 7.5
# software id = xxx
#
# model = RouterBOARD 750G r3
# serial number = xxx
/ip firewall nat
add action=masquerade chain=
Are this done to be backward compatible to 6.x?
