Question: Need help to search into a chunk of character.

Hello to all,

I have a chunk of letters, numbers and others symbols like in this extract:

.....XRIH*zAv/(z*Bf3)+3*AkQ4xBpTbCYJVq6qCRRUYJy1aBvSjuQXp+zr6kmMEuNR+9*u9zugTalYwXJA*mBhaiM+8*WrkyyflSAs0JssjHLArZ+l5M1sWtcMznmkmu1+NmmSb7dsacr3qJkzQH*dE3yQlI0Ly2RGa1*Yr/ZlvZFCwCiQyVTQ2GflsnOBZTf05W4Ul35uZMHFxhy1tipPyK+iHfus/mJVhEeluq9vtVzEzwbPWav+w11/ii14f78yXqsqH+XU2m....

My goal is to be able to enter that chunk into Maple for character manipulation like searching if, for example, Qxp+zr6km is part of that chunk as is (and if possible his location).  Since there is some "+", I can't define it with chunk :=.  The source is a *.txt file.  Maybe a readdata?

I am quite busy for the moment so is there someone kind enough to help me.

Thanks in advance
