Re: line too long

[Steve Knox <stevek@xxxxxxxxxxxxxxxxxx>]

I tried using \ to make the line more readable but am still getting "line
too long".
I seem to be well under the limit of 2048 chars.

use "/data/ojima/Web/vemap2/olsoncoverages/in/oge10km.cdf"
set window/aspect= .65
let cover2 = IF cover eq 1 \
 or cover eq 2 \
 or cover eq 3 \
 or cover eq 5 \
 or cover eq 7 \
 or cover eq 8 \
 or cover eq 9 \
 or cover eq 12 \
 or cover eq 13 \
 or cover eq 14 \
 or cover eq 15 \
 or cover eq 17 \
 or cover eq 20 \
 or cover eq 21 \
 or cover eq 22 \
 or cover eq 23 \
 or cover eq 24 \
 or cover eq 25 \
 or cover eq 26 \
 or cover eq 27 \
 or cover eq 29 \
 or cover eq 30 \
 or cover eq 31 \
 or cover eq 32 \
 or cover eq 33 \
 or cover eq 34 \
 or cover eq 35 \
 or cover eq 37 \
 or cover eq 38 \
 or cover eq 40 \
 or cover eq 41 \
 or cover eq 43 \
 or cover eq 46 then cover
 **ERROR: line too long: q 46 then cover

If I shorten it a bit as:
let cover2 = IF cover eq 1 \
 or cover eq 2 \
 or cover eq 3 \
 or cover eq 5 \
 or cover eq 7 \
 or cover eq 8 \
 or cover eq 9 \
 or cover eq 12 \
 or cover eq 13 \
 or cover eq 14 \
 or cover eq 15 \
 or cover eq 17 \
 or cover eq 20 \
 or cover eq 21 \
 or cover eq 22 \
 or cover eq 23 \
 or cover eq 24 \
 or cover eq 25 \
 or cover eq 26 \
 or cover eq 27 \
 or cover eq 29 \
 or cover eq 30 \
 or cover eq 31 \
 or cover eq 32 \
 or cover eq 33 then cover
 **ERROR: expression too complex:A

So I'm wondering if the problem is not line length but too many
conditional expressions??
In general I won't have consecutive values so I can't shorten an
expression like "if cover eq 1 or cover eq 2 or cover eq 3 or cover eq 4"
to
"if cover ge 1 and cover le 4"
