[Bug-gnucap] "no match" error attempting to printing named nodes

[Kenelm L. McKinney]

Hi,

I am having a simple problem which I think is a bug.  Before starting the
process of fixing it I thought I would see if anyone on the list has seen
the problem, fixed the problem, or has any thoughts on the problem.

Summary:
  Running gnucap-0.33
   When using "numbered nodes"  circuit simulates correctly and prints node
values correctly.
   When using "named nodes"        circuit simulates correctly  but gives
"no match" errors in .PRINT statement

Here is short test that shows problem:
do "sh  x.sh"

Here are the relevant files
  x.sh
  x.gcap
  good.ckt
  bad.ckt
  log


x.sh:
#This demonstrates the problem
gnucap <x.gcap >log
grep -n "no match" log
#Note the "no match" problem at lines 66 and 68
#The simulation runs correctly but the print command is troubled...

x.gcap:
opt nonamednodes
options
<good.ckt
clear
opt namednodes
options
<bad.ckt

good.ckt:
GOOD
V1 999 0 1
R1 999 0 1
.PRINT AC  V(999)
.PRINT DC  V(999) I(V1)
.DC V1 1 2 0.1
.end

bad.ckt:
BAD
V1 NodeB 0 1
R1 NodeB 0 1
.PRINT AC  V(NodeB)
.PRINT DC  V(NodeB) I(V1)
.DC V1 1 2 0.1
.end
