Some modern dialects, such as [[APLX]] and [[GNU APL]], are based on ISO/IEC 13751:2001, while others, such as [[APL+Win]] and [[Dyalog]], have a slightly different set of [[quad name]]s and provide the [[migration level]] functionality to improve compatibility.

In a 2005 study (prior to the existence of GNU APL, as well as the addition of features from the standard to various dialects), the obscure dialect [[APL2C]] was found to have the fewest features differing from the standard, followed by APLX and [[APL2]].<ref>F.H.D. van Batenburg.
