The [[LINE INPUT]] statement requests a [[STRING]] keyboard entry from a program user.


{{PageSyntax}}
: [[LINE INPUT]] [;] "[text prompt or question]"{,|;} {{Parameter|stringVariable$}}
: [[LINE INPUT]] ; {{Parameter|stringVariable$}}


{{Parameters}}
* A [[semicolon]] immediately after LINE INPUT stops the cursor after the entry and prevents screen roll on the lowest two screen rows.
* ''text prompt or question'' is optional, but quotes are necessary unless just a semicolon is used before the {{Parameter|stringVariable$}}.
* Requires only one [[STRING|string]] variable to hold the entire text entry.


{{PageDescription}}
* Cannot use numerical [[type]] variables or [[comma]] separated variable lists for multiple entries.
* Allows [[comma]]s and [[quotation mark]]s in the user input, unlike [[INPUT]] where commas denote extra input values and quotes delimit strings. 
* The statement halts the program until an entry is made. Pressing Enter ends the entry and code execution resumes.
* LINE INPUT does not trim off leading or trailing spaces in the string entry like [[INPUT]] string returns.
* Use [[VAL]] to convert string numbers and [[&amp;O]] (octal), [[&amp;H]] (hexadecimal) or [[&amp;B]] (binary) prefixed entries into numerical values. 
* Use [[_DEST]] [[_CONSOLE]] before LINE INPUT statements to receive input from a [[$CONSOLE|console]] window.
* '''Note: QB64''' will not remove CHR$(0) from the end of LINE INPUT string return values like QBasic did.

: ''Explanation:'' The {{text|red|red}} [[semicolon]] after LINE INPUT acts like a semicolon after a [[PRINT]], which keeps the print cursor on the same row.
