On equipment, especially calculators, the lozenge is used to mark the subtotal key. It is standardized in ISO 7000<ref>ISO 7000 - Graphical symbols for use on equipment</ref> as symbol ISO-7000-0650 ("Subtotal"). In a similar fashion, the square lozenge (⌑), part of the [[BCDIC]] character set, was often used on tabulation listings to indicate second level totals in banking installations in the 1960s.<ref name="Mackenzie_1980">{{cite book |url=https://textfiles.meulie.net/bitsaved/Books/Mackenzie_CodedCharSets.pdf |title=Coded Character Sets, History and Development |series=The Systems Programming Series |author-last=Mackenzie |author-first=Charles E. |date=1980 |edition=1 |publisher=[[Addison-Wesley Publishing Company, Inc.]] |lccn=77-90165 |page=99 |isbn=978-0-201-14460-4 |access-date=2019-08-25 |archive-url=https://web.archive.org/web/20160526172151/https://textfiles.meulie.net/bitsaved/Books/Mackenzie_CodedCharSets.pdf |archive-date=May 26, 2016 |url-status=live |df=mdy-all }}</ref>
