INPUT
Syntax
INPUT var [,length [ _ ]] [:] [{FOR | WAITING} time.expr] [UNFILTERED]
[THEN statements | ELSE statements]
INPUT var [,-l] [{FOR | WAITING} time.expr] [UNFILTERED] [THEN
statements | ELSE statements]
Description
The UniBasic INPUT command requests data from an input queue or from the
terminal screen. INPUT supports multibyte languages.
If INPUT is successful, UniData sets @SYSTEM.RETURN.CODE to 0. If unsuccessful
(the INPUT statement with a FOR or WAITING clause timed out), UniData
sets @SYSTEM.RETURN.CODE to -1.
One variable is read by each INPUT statement. If you press ENTER in response to
an INPUT statement, an empty string is assigned to the variable.
Tip: Precede INPUT with a PRINT statement to display a prompt.
UDT.OPTIONS 83 enables the escape character (usually ASCII code 27) to be
accepted by INPUT while screening out or converting other control characters.
THEN | ELSE is associated with the WAITING clause except in the case described
in the following warning note.
