How to remove the first character from a variable in routerOS (mikrotik)?

Question

Mikrotik

"I am writing" a bot for Mikrotik with receiving commands via telegrams. Found a few bots and copy-pasted them. The bot works fine, but when I started to bring beauty I ran into a problem.
I don't understand how to parse text into a command without the "/" character.
