Multi line strings assignment
Multi line strings are a fringe feature of programming languages. They are very rarely needed, so a lot of languages don't support them at all. And even when a language does support them, most programmers are not even aware of that. How often have you seen something like this in real code:
DIM myStr AS STRING = "This is a thinBasic
multiline string
just because I can!"
To simplify assignment of multi line text strings to string variables, thinBasic support 2 distinct ways:
1.double quote multi line
2.RAWTEXT keyword
1. Double quote multi line
To use this method just set a double quote at the beginning of the multi line string and than set another double quote char at the end of the string in a different line of the code. thinBasic will join all the lines found between the 2 double quotes.
Example:
DIM MyString AS STRING = "<r><![CDATA[
The text string goes here. Since this is a XML CDATA section,
stuff like <> work fine too, even if definitely invalid XML.
]]></r>"
Important: if you want to use single quote inside in multi line string as real char, just start with multi line string with a single quote, than enter a new line, type your multi line string and terminate it again with a single quote in a new line.
Example of double quotes inside multi line string:
DIM MyString AS STRING
MyString = "
<r><![CDATA[
"The text string goes here. Since this is a XML CDATA section,
stuff like <> work fine too, even if definitely invalid XML."
]]></r>
"
Deprecated |
RAWTEXT has been deprecated in favor of multi line strings |
2. RAWTEXT keyword
To use this method use RAWTEXT / END RAWTEXT keywords pairs block to enclose a multi line string.
Example:
DIM MyString AS STRING = RAWTEXT
<r><![CDATA[
The text string goes here. Since this is a XML CDATA section,
stuff like <> work fine too, even if definitely invalid XML.
]]></r>
END RAWTEXT
Rules for using RAWTEXT / END RAWTEXT
1.in case RAWTEXT is an assignment, it MUST begin on the same line of the assignment
2.no line continuation sign before RAWTEXT
3.after RAWTEXT there MUST be a a new line
4.END RAWTEXT MUST be on a line without any other text
