Holger Vogt 761da8ad0e revert polarity of current mesurements: 
current positive when flowing into device, e.g.
Ic, Ib of a positively biased npn.

Add current measurement for all nodes of a device,
e.g. .probe i(Q1) will measure Ic, Ib, Ie (and Is)
 2022-04-22 17:46:55 +02:00

Holger Vogt 2aa950fe9c Remove a conflict between the text variable substitution like 
set text = "mytext"
set newtext = new.{$text}
echo $newtext
and the command circbyline, which may have to process strings
containing braces {...} without any change to the string.

Do not call cp_doglob() when command circbyline is executed.

Holger Vogt 9deb9f51d8 In case of resistor valuues r150 (r + integer number), 
return 150
R2 n1 n2 r150

In case of r23mod return error = 1 and val = 0, so
r23mod may be read as a model, not an instance parameter
R3 n3 n4 r23mod
