Hello,

 

 

These days,I am playing with Tree grammar, I got the error today:

 

F:\Treegrammar.g: node from after line 9:15 required (...)+ loop did not match anything at input 'UP'
F:\Treegrammar.g: node from after line 9:15 mismatched input 'MULTIPLICATIVE_EXPRESSION' expecting <UP>

 

what does  'UP' AND  <UP> mean?

 

 

 Thanks in advance.

 

 

 Annie
