There are many different methods of checking for valid numbers or dates in a character variable; from writing a validation macro to just using an input statement and hoping for the best. Wouldn't it be useful if there were an easy to use SAS(R) function that would check if a character ...
It requires the following SAS products: SAS/FSP®, SAS/AF®, SAS/GRAPH®. Conclusion It is important that business critical applications continue to function as expected come year 2000. Find2000 can help build an inventory of potential year 2000 problems. The search capability of Find2000,...
Using the INPUT Function Use the INPUT when you have a SAS text variable in a DATE informat convention. You can transform it to a SAS date by invoking the INPUT function with the appropriate informat: data mdytest; begin_sugi = input ('4/9/2000',mmddyy8.) ; tutor_date = input ('...
