I am passing some debug text from java to SDL via a declare.  Tonight I
added more than two lines of text to the concat/declare and the result
is truncated.

The doc says each individual string literal is max 256 chars. I see no
limit on the concat.
Regardless, this one is tipping over at the 156 character mark.

In the following, the #debug "======\n" line is not part of the
questioned text, and occurs later in processing and is used to
demonstrate the missing \n from the questioned text.

SDL:

#declare ThrustDebugText=concat("Using file
/pov/tteo2015/data/ttlo/thrust/23.976/_th-1045.inc\n    for clock =
93.05800000001197\n",
"    updateLocoPosition MecoStart vel=decel\n",
"    updateLocoPosition MecoStart vel=decel\n",
"    updateLocoPosition MecoStart vel=decel\n",
"    updateLocoPosition MecoStart vel=decel\n",
"    SpaceLocoVec=<110.00, 381.85, 20.00> CabooseVec=<110.00, 368.35,
20.00>\n"
);

output:

Using file /pov/tteo2015/data/ttlo/thrust/23.976/_th-1045.inc
    for clock = 93.05800000001197
    updateLocoPosition MecoStart vel=decel
    updateLocoPos...============================


The shorter (two line) #concat works as expected.

SDL:

#declare ThrustDebugText=concat("Using file
/pov/tteo2015/data/ttlo/thrust/23.976/_th-1001.inc\n    for clock =
91.21800000001103\n",
"    SpaceLocoVec=<110.00, 355.74, 20.00> CabooseVec=<110.00, 342.24,
20.00>\n"
);

output:

Using file /pov/tteo2015/data/ttlo/thrust/23.976/_th-1001.inc
    for clock = 91.21800000001103
    SpaceLocoVec=<110.00, 355.74, 20.00> CabooseVec=<110.00, 342.24, 20.00>
