Hi, there.  
I like programming using stack.  
I want to read stack and, depending of the entry value, delete it.  
I have found terminal commands documentation such as %.P and %.S.  
Unfortunately, I haven´t found any example about it.  
Please, do you know how to use stack to read or delete an entry ?  
Thank you.

take a look at the SET CONTROL statement.

Once you issue SET CONTROL ‘%.S’, you use an INPUT statement to read the contents (you can use \*DATA to see how many elements there are). Issue the SET CONTROL ‘%.P’ to delete the next entry on the stack (which, if you have just used ‘%.S’, will be the entry you just read).
