Inodzorera kukosha kwekushanduka varName . Kana kukosha kuri kujekeswa, edzai kukosha kwevarName kukoshesa , kugadzira zvitsva zvitsva kana munhu asati atovapo, uye kudzorera kukosha kwayo. Kana varName ine mazera ekuzarura uye inoguma nevana vekupedzisira, zvino inoreva chinhu chakasiyana-siyana: mavara asati agona kuberekwa mazita ari mazita evanhu, uye mavara pakati pevabereki ndivo inotenderera mukati memazana. Kana zvisina kudaro varName inoreva kushandiswa kwemavara . Kazhinji, varName haina kukodzera (haina kusanganisira mazita chero ipi zvayo ane mazita emazita), uye kushandiswa kwezita iroro mune mazita anonyanya kuverengwa kunoverengwa kana kunyorwa. Kana varName inosanganisira namespace qualifiers (muzita rakagadzirirwa kana iri kureva chinhu chinowanikwa), zvinoshandiswa pane zvinyorwa zvinonzi mazita zvinowanikwa kana zvakanyorwa.
Kana pasina nzira inoshandiswa, ipapo varName inoreva mazita e-variablepace (pasi rose kana iyo mazita manje ari nzvimbo yepasi rose).
