How to convert variables which can handle both numeric and character data?

[Rakesh93]

I have a lab dataset in which LBSTNRHI, LBSTNRLO, LBREFID , LBSTNRHI_US, LBSTNRLO_US are there. I want to convert these variable so that they could handle both character data type as well as numeric data type. Kindly share your answers with programming code.

Thank you.

Only SAS character variables can store both character and numeric data. Use PROC CONTENTS to confirm if your variables are either character or numeric:

proc contents data = MyLib.MyTable;
run;

I have mentioned those variables in message. I want only those variables
can read both numeric and character data. Do you know any formats which can
Achieve that?

If LBSTNRHI, LBSTNRLO, LBREFID , LBSTNRHI_US, LBSTNRLO_US are character variables then they can store both character and numeric data. Use PROC CONTENTS as I showed you to confirm if they are character or not.
