Reads one line of input from the keyboard
Syntax
Line Input [;] [promptstring {;|,} ] stringvariable
Parameters
promptstring
optional prompt to display before waiting for input. If it is followed by a semicolon (;), a question mark ("? ") will be appended to the prompt. If it is followed by a comma, nothing will be appended.
stringvariable
variable to receive the line of text
Description
Reads a line of text from the keyboard and stores it in a string variable.
The
promptstring - if any - is written to the screen at the current cursor location, and characters read are echoed to the screen immediately following the prompt. If no prompt is specified, characters are echoed at the current cursor location.
The optional leading semicolon (
;) after
Line Input is similar to the optional trailing semicolon in a
Print statement: the cursor will remain on the same line after all of the characters have been echoed, otherwise, the cursor will move to the beginning of the next line.
Line Input has a limited edit capacity: it allows to use the left and right cursor keys to navigate the text, and to erase or insert characters. If a better user interface is needed, a custom input routine should be used.
Example
Dim x As String
Line Input "Enter a line:", x
Print "You entered '"; x; "'"
Differences from QB
- QBASIC only allowed literal strings for the prompt text. FreeBASIC allows any variable or constant string expression.
