Many thanks for the information. For my issue, warning is caused by a character "≥ " in a xlsx file, when I use libname to convert it into SAS dataset. The original text in the xlsx file is"≥ 9 g/dL" and the imported text in my work sas file is " 9 g/dL". Here is my code: %let inxls=path/ final.xlsx; libname inxls xlsx "&inxls"; proc datasets lib=inxls nolist; modify PDANDAI / CORRECTENCODING='utf-8'; quit; Here give my ERROR: ERROR: Update access is not supported for file INXLS.PD_AND_AI.DATA. data a; set inxls.PDandAI ; run; could you please let me know how I modfy the program to get this resolved? Many thanks for your help!
