sas and csv files numbers to txt and scientific notation

Greetings -I tried to make things easy and wound up complicating it instead. I took a long number and put it in a csv file from sas to make it a txt and then imported it back to sas....trouble was csv made it into a scientific notation which wont work and now I need to reverse engineeer it back so I can first get the original number then keep it in sas and use a put statement to change it to a txt.

Any help greatly appreciated and the next time I will keep it in SAS!
