https://www.autohotkey.com/docs/v1/lib/IfEqual.htm#Remarks
Note that command-like If statements allow a command or command-like control flow statement to be written on the same line, but mispelled command names are treated as literal text. In other words, these are valid:

IfEqual, x, 1, Sleep, 1
IfGreater, x, 1, EnvAdd, x, 2

TODO

• format, if has command in the same line, next line not indentation.
• diagnosis, like IfInString x, a Sort, MyVar , the a and sort miss comma.

Named If statements allow a command to be written on the same line, but mispelled command names are treated as literal text. Such errors may be difficult to detect.
