The following equate is used starting with the earliest preprocessing
|

|
|
to handle the case of two lines with quoted strings that are joined
|
||
|
|
by a line continuation character. The result is something like
|
||
|
|
"abc""def" -- which evaluates to abc"def. So DQUOTE is used to start and
|
||
|
|
end a quoted string, and the " character is used where a " character is
|
||
|
|
actually part of the string.

because the buffer is reallocated as it grows and thus may move.
