Macro variables are just a text substitution mechanism. When you execute SAS code, the value of the macro variable (a text string) is substituted into SAS code (where the macro variable was in the code), and this substitution of macro variable value into the code MUST produce valid working ...
What is the way to concatenate two macro variables without space between them in %let statement? %let a_b=&a.&b.; is not good because there is space between them? Why space is created here? %let a=783; %let b=9828888223; %let a_b=&a.&b.; /**No good due to space**//**...
