Dear all, 
I would like to generate new variables using this command:
for var  X1-X50 :replace X_new=1 if X=="New" 
But some Xi variables are numeric because empty
This command stops when one of the Xi is numeric 
How can I ask to execute this command only for string Xi variables ?  Is
there a "format" function which returns the type of the variable ? If this
exists, I could use:
for var  X1-X50 :replace X_new=1 if X=="New" & format(X)==string
Thank you
Alvine Bissery
