Introduction
Similar to Python and other modern programming languages, B4P supports multline strings, for both
- Text inside single quotation marks, using three single quotation marks ''' (apostrophes) as delimiters, and
- Text inside double quotation marks, using three double quotation marks """ as delimiters.
Following rules apply for multi-line text items:
- The text contents are treated similarly as defined for Text inside single quotation marks and Text inside double quotation marks.
- Inside a multi-line text, 1 or 2 consecutive' or " symbols are treated as contents.
- Inside a multi-line text delimited with """: The ''' is considered part of the text.
- Inside a multi-line text delimited with ''': The """ is considered part of the text.
- Similar to text inside single quotation marks, character entities are supported.
Multi-line string contents can start immediately after the three quotation symbols or on the next row. Same applies for the
end: The multi-line string can be ended on the same line with three quotation marks, or immediately on the following row.
If you want to include new line symbols at the beginning and/or at the end of the multi-line string, then include additional
blank rows.
Attention: If the multi-line string is not properly delimited with the same triple quotation marks, then an error message
will occur at the end of the B4P program file because B4P assumed all contents further down as part of the long string.
