+ Push the currently active CPU onto a stack. The stack has a size of 8
+ entries.
+
+ <tt/.PUSHCPU/ allows together with <tt><ref id=".POPCPU"
+ name=".POPCPU"></tt> to switch to another CPU and to restore the old CPU
+ later, without knowledge of the current CPU setting.
+
+ The assembler will print an error message if the CPU stack is already full,
+ when this command is issued.
