### Help me backslash

Hello,

I got a working latex code (got from somebody) which has this syntax:
CODE:
`[SELECT ALL] [EXPAND/COLLAPSE] [DOWNLOAD] (UNTITLED.TEX) OPEN IN OVERLEAFnewcommand* \{\ABC} \{ABCDEFG}`

As I understood, the backslash removes the white space. But I am getting error due to the two backslashes outside {}.

Any suggestions?

Thanks.

This is not a valid latex code. Errors are expected. Seems like some parser removed and added backslashes.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

Welcome to the forum!

The correct syntax is:

`\newcommand*{\ABC}{ABCDEFG}`

A backslash is used for commands and macros (so called "control sequences"). Everything that starts with a backslash \, is a command or macro (well, control sequence in TeX speak). This line above creates a macro called `\ABC`, that contains the text ABCDEFG.

If you would see stuff like `\(`, `\[`, or `\{`, these are actually macros too, just short.
