* The quotation mark must delimit the ends of a string or text prompt in a [[PRINT]], [[WRITE]], [[INPUT]] or [[LINE INPUT]] statement.

* The IDE may add  a missing quotation mark at the end of a [[SUB|statement]] or [[FUNCTION|function]].
 
* [[LINE INPUT]] allows quotation marks to be entered as user input. The [[LINE INPUT (file statement)]] can transfer quotation marks.
 
* Quotation marks should be used when [[comma]]s are used in a literal [[WRITE]] or [[INPUT (file statement)]] text string.
 
* To insert quotation marks in a [[PRINT]] statement insert [[CHR$]](34) using string [[concatenation]] or [[semicolon]]s.
 
* String values can be [[concatenation|concatenated]] or added using the plus ([[+]]) operator. Cannot be used to combine numerical values!
 
* Concatenation MUST be used when combining literal [[STRING|string]] values in a variable definition.
 
* String values can be combined with other string or numerical values using [[semicolon]]s or [[comma]] tabs in a PRINT statement.
 
* Literal [[DATA]] strings do not require quotation marks unless the value is a keyword, uses commas or has end spaces.

Example: Coverting Radian into Degree.

INPUT "Give me an angle in Radians ", D R = _R2D(D) PRINT "That angle in Degrees is "; R

Give me an angle in Radians 0.5 That angle in Degrees is 28.64789
