lj set element name justification

This attribute controls the width of set element names in the put output.  It is addressed using the syntax

Localfileidentifier.lj=number;

or in the example putex9.gms

my1.lj=3;

where 1 is for right, 2 for left and 3 for center.

Example:

Using the sequence (putex6.gms)

set mine abcdefghijklmnopqrstuvwxyz

/a1  seta1

 b12345678901234567890  setbabcdefghijklmnopqrstuvwxyz

 small/;

loop(mine,

put 'start set element name here $':0 mine.tl:20 '$ end here'/;)

put /;

where the items in orange are set element text and the blue items are statements causing those to be output into the put file. In turn, with the default for .lj of 2 we get

start set element name here $a1                  $ end here

start set element name here $b1234567890123456789$ end here

start set element name here $small               $ end here

where narrow text entries like a1 and small are flushed left, but the long names like a12345678901234567890 just fill the field.

If we reset lj to 1 we get

start set element name here $                  a1$ end here

start set element name here $b1234567890123456789$ end here

start set element name here $               small$ end here

where we see the narrow entries flushed right.  If we reset lw to 3 we get

start set element name here $         a1         $ end here

start set element name here $b1234567890123456789$ end here

start set element name here $       small        $ end here

showing centering of the narrow entries.
