IF ELSE and Comments

[Bodo Schulz]

What's wrong with these lines, on CMD it works

@IF "A" = "A" @(
@ECHO True
) ELSE @(
@CD .
)

What's with the @ signs in front of the parentheses?

 

[Bodo Schulz]

no command output when executed
so i reduce output while debugging

 

[Bodo Schulz]

@IF "A" EQU "A" (
@ECHO True
) ELSE (
@CD .
)

in CMD it's allowed to mark a commandblock () with @ to disable output (ECHO OFF) of a whole block, like
@IF "A" EQU "A" (
ECHO True
) ELSE @(
CD .
)

In practice, i disable any possible output and enable areas where i must debug

Depending on the number of @s, it might be more efficient to use "echo off" and "echo on" .. yes/no?

It's a 200 KByte file and selective activating was an helpfull function
and by the way it's an incompatibility ;-)

 

[Bodo Schulz]

It's like
@FOR ... DO (...)
or
FOR ... DO @(...)
different output

@	As the first character in a line: Do not save the current line in the history list when it is executed, nor store it in the CMDLINE environment variable.
