Reading part of a (varying) filename into SAS dataset field, seperated by "_"

[Lakes74]

Hello all,

I have a large number of files where part of the information i require is held within the filename rather than contents of that file.

Eg: X1234567_AAA1_21112012.txt. I require the part at the first part (X1234567) ending before the underscore, which is straight forward to obtain.

The problem lies in the varying length of info, some are 8 cahrs long, others are 10 chars and longer.

I need to extract this information up to the point of the first underscore is displayed. This applies to all of the files.

Was thinking of using the Scan option but can't work out how to incorporate ine info before the underscore.

Thanks in advance.

Scan () is the function to use.  Scan(name, 1, '_') ; shou dgive the required info.  Third parameter specifies the delimiter.
