ECHO

The ECHO statement will turn on or off the echoing of characters typed at the keyboard.

COMMAND SYNTAX

    ECHO ON

    ECHO OFF

    ECHO expression

SYNTAX ELEMENTS

Use the statement with the keywords ON and OFF to specify echoing or not. If used with an expression, then the expression should evaluate to a Boolean TRUE or FALSE result.

TRUE: echoing on

FALSE: echoing off.

NOTES

Use the SYSTEM function to determine the current state of character echoing. SYSTEM(24) returns Boolean TRUE if enabled and returns Boolean FALSE if disabled.

EXAMPLES

    ECHO OFF
    CRT "Enter your password " :
    INPUT Password
    ECHO ON
    .....

This will disable the character input echoing while typing in a password.

TAFJ R23 note: user input can be seen after Enter is pressed, even without ECHO ON at the end.
