[in] | v | additional informations regarding parametric symbols |
The v
argument is required for parametric symbols (i.e. for a numeric terminal we have to print 123 rather than "NUMBER").
Reimplemented from vita::terminal.

true
for parametric symbolsGenes associated with parametric symbols store an additional parameter fetched at run-time and used for symbol evaluation.
