Format

pop2

Forms

pop2 = 60 (0x3c)

Stack

…, word2, word1 → …

Description

The top two words are popped from the operand stack.

The pop2 instruction must not be used unless each of word1 and word2 is a word that contains a 16-bit data type or both together are the two words of a single 32-bit datum.

Notes

Except for restrictions preserving the integrity of 32-bit data types, the pop2 instruction operates on an untyped word, ignoring the type of data it contains.
