Why I can't CALL "IF" and "FOR" neither in batch nor in the cmd?

You are quite right.

FOR, IF and REM aren't normal internal commands (but for REM exists also a normal internal version).
They use an own special parser (each a different one).

It seems that these commands are translated to a sort of token.
Therefor you got such unexpected error messages (there are much more possible characters), the error/token character depends also of the Windows version (if I remember correct here).
Probably the CALL command sees only the tokenized data from the original command.

Command blocks don't work at all with the call command, also &|<> don't work as expected.

call (a^|a)

Searches for a command/token 2, so if you create a batch file named 2.bat you can start it with call (a^|a).

Dostips:Limit CMD processing to internal commands, safer and faster?

After all it is possible to call IF and FOR ..or almost;

    @echo off

rem :: this will produce an error
rem if a equ a

rem :: And this too
rem call if a equ a rem

rem :: But this will not!!!
call if a equ a

rem :: This will not too ((\but in command prompt single % is enough)
call for %%%%a in (.) do

rem :: And this
call if a equ a for %%%%a in (.) do if 1 equ 1  for %%%%a in (.) do if c==c

rem :: And this
call if a equ a for %%%%a in (.) do if 1 equ 1 for %%%%a in (.) do if c==c ( rem rem rem echo something

Despite I see no usage of this.
