At all points in IMPORT input files, the following characters have special significance.
; ! * Comment characters. All text on a line after one of these is met is ignored. + Continuation characters. Lines are concatenated if this character is found. Blank lines are always ignored, as are superfluous spaces and tab characters.
IMPORT is not case sensitive - if case is required to be preserved, for example in keyword data, then the text should be enclosed in double quotes.
