Hi Pinku,
Try this,
"USING: kernel ; 1 1 + drop ;" eval>string print
It outputs
"""
1: USING: kernel ; 1 1 + drop ;
^
No word named ``+'' found in current vocabulary search path
The following restarts are available:
:1 Use the math vocabulary
:2 Defer word in current vocabulary
Type :help for debugging help.
"""
There's no way to change the default vocabularies for eval.
