Hi!

How can I  access the nth input line expression unevaluated without
using InString?

I am driving the Mathematica kernel via J/Link by sending multiple
EnterExpressionPackets to the kernel. Later I want to access a
preceding input expression in its unevaluated form. Because expression
packets aren't strings the kernel does not seem to assign them to
InString[n] but only records them in In[n]. When calling In[n] later,
how can I prevent In[n] from re-evaluating  the input line and make it
return the input expression unevaluated?

Thanks,
Sascha
