Text not displaying completely in AL11

Hi Guys,

I i am trying to upload a file in AL11 but the data is not displaying completely in AL11 but it is showing correctly in print preview for that invoice (VF22).

I have used the below statement to open the Data set, can you please advise on what can I do to resolve this issue.

"OPEN DATASET fname FOR APPENDING IN LEGACY BINARY MODE CODE PAGE '1100'."
