 * Charge `gas_mulmodx(active_context.element_size / 8) * count` and copy the values into EVM memory starting at offset `dest`, laying them out in big-endian ordering, padded such that size of each is a multiple of 64 bits.

 **Stack in**: `dest source count`
+
 **Stack out**: none
+
 **Description**: copies values layed out in EVM memory as 64bit-aligned big-endian numbers into a contiguous section of the currently-active field context's value space.
+
 ##### Execution
 * Assert that a field context is set as active in the current call frame.
 * Assert `dest + count` is less than or equal to the active context's value space size.
