The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
|25||dup||Duplicates the value on the top of the stack.|
The stack transitional behavior, in sequential order, is:
valueis pushed onto the stack.
valueis popped off of the stack for duplication.
valueis pushed back onto the stack.
A duplicate value is pushed onto the stack.
dup instruction duplicates the top element of the stack, and leaves two identical values atop it.
