When you inquire about a line, the value returned is the string of text found on the specified line number of the specified textual region. For example, if you define a textual region and put text into the region as follows:
textual region Manual size 400 400 at position 10 10
insert "This is line one\nThis is line two"
and later specify in the program:
response to ...
copy textual line 1 from Manual to CurrentLine
ESL copies the following string value to CurrentLine:
"This is line one"
Note that the string does not include the newline sequence (\n).
