Yes. I am new to SAS. But can understand the existing code by google.

Thanks for the clear explanation. Another problem why it truncated was due to SYMGET function. But not sure why it truncates. So i declare length function for that symget varible and Also for new variable as you said. After that i got correct outptut. But want to know the reason Why symget truncates the string

From the documentation of the SYMGET Function:

If the SYMGET function returns a value to a variable that has not yet been assigned a length, by default the variable is assigned a length of 200.

There is a VERY BIG reason why Maxim 1 (Read the Documentation) is number one. It is the most important and most helpful rule for people working with SAS.
