[gradsusr] mysterious scripting error

[Jeff Duda]

Gary,
Thanks for your reply.

Yes, it is my own personal script. Here is the code for assigning the
arrays:

'set gxout print'
'set prnopts %g 1'
'd 2.5e6*qvapor'
tt = 1
while (tt <= nt)
 lvq.tt = sublin(result,blank_lines+tt)
 say tt" "lvq.tt" "nt
 tt = tt + 1
endwhile
'd 1005*(t+300)'
tt = 1
while (tt <= nt)
 CpT.tt = sublin(result,blank_lines+tt)
 say tt" "CpT.tt" "nt
 tt = tt + 1
endwhile

Output from this portion is shown as:

1 43504.7  13
2 43400.9  13
3 44271.9  13
4 42382.9  13
5 42426  13
6 40946.4  13
7 37313.4  13
8 32887.1  13
9 30245.9  13
10 30008.8  13
11 28724.1  13
12 29439.1  13
13 28436.3  13
1 302984  13
2 303499  13
3 304544  13
4 306799  13
5 307953  13
6 309824  13
7 311769  13
8 313546  13
9 314621  13
10 315541  13
11 316056  13
12 316285  13
13 316526  13

so in this script instance, nt is set to 13 (and I checked the code to make
sure nt doesn't get changed later on in the script, and it doesn't), and
CpT.nt = CpT.13 = 316526. I added
say CpT.nt
just before the code line where the crash is occurring. It prints
accurately. However, the very next line...Grads just doesn't like it.

I'm running the pre-compiled version 2.1.a3 on Linux. Not sure if it's the
CentOS5.9 or the i686 compilation, though.
