I would like an appropriate explanation of what Long and Long Strings are, even though they may be small resources.

Long Comments are comments using Long Format . Long Strings represent strings, but also using Long Format.
Long Format
Long Format is a format that differentiates between versions -5.1 and +5.2.
In this version, the format starts with the string [[ and ends with the sequence ]] related (the same pairs can be repeated inside).
In this version the format receives a lock level. The format only starts if its start is valid. The beginning starts with [ and counts the = symbols until ] appears to finalize itself. If there was any character outside = and [ , then the format does not start.
The lock level will be the amount of assigns ( = ).
The end of the format is similar to the start, it only changes [ to ] and requires the same amount of assigns.
Long Comment
Nothing special about your format, other than the format should be declared after -- .
Long String
The format of the long string does not interpret escape ( \ ), requires an end, and has two background actions:
-
Converts the string of bytes
0D 0A(carriage return and new line, \ r \ n) and byte0D(\ r) to0A(\ n) li> -
Ignores the first line break (
0D 0A,0Aor0D) followed by its start
The language interpreter assumes that the bytes of the target code are character codes, so any future problems relate to the encoding of their characters.
