ligature
(lig' u chu^r) n.
a letterform for two or more consecutive characters, to provide alternate shapes for these characters when they appear in sequence. Traditional typefaces may provide ligatures for ff, fi, fl, ft, ffi, and ffl.
light emitting diode
n.
a semiconductor diode that emits light when an electric current is applied.
Also, light-emitting diode. Abbr. LED.

1. a sequence of characters arranged horizontally.
2. a record in a program file or other text file.
3. a long, narrow mark, or a geometric shape formed as a continuous set of points having only elongation, with no thickness, corners, or curvature.
4. a queue.
LINE
SAS/GRAPH. Annotate variable.
linear
(lin' E ur) n.

line mode
line command
n.
a command that is entered in the line number fields of a text editor window and is applied a line or several consecutive lines of a text file being edited.
LINESIZE
System option. Ref: PSPPR:System Options. PSPL:Print Output:Print Files and Pages. SLRD:SAS System Options. Alias, LS.
link
(lingk'), v.t.
to combine compiled routines to create an executable program.
linker (lingk' ur), n. A linker may be a separate program or a component of a compiler.

Linux
(lin' uks, lIn'-) n.
an operating system developed as an open source project in the late 1990s, based on a kernel by Linus Torvalds, designed to be mostly compatible with Unix. Linux is the operating system used on most Internet servers.
liquid crystal diode
n.
a segment of liquid crystal used as a diode that absorbs light in varying degrees depending on the electric current that is applied.
Abbr. LCD.
LIST
Data step statement. Ref: PSPPR:Data step statements. PSPL:Control Flow:Shaping the Observation Loop. SLRD:Statements.
Display Manager window. Alias for LISTING.
list ID

list input
n.
input of a variable from a text file, reading the value from a field that is delimited by spaces or another delimiter character. In an INPUT statement, a variable name without an associated informat or modifier indicates list input.
list output
n.
output of a variable to a text file, writing the value with leading and trailing spaces removed and skipping a characer position after the value. In a PUT statement, a variable name with no associated format indicates list output.
LISTTASK
Global statement. Ref: PSPPR:Global Statements. PSPL:Execution:Session.
