Kufotokozera
Ibwezera mtengo wa variable varName . Ngati mtengo waperekedwa, pangani mtengo wa varName kuti ukhale wofunika , ndikupanga kusintha kwatsopano ngati palibe kale, ndikubwezeretsanso mtengo wake. Ngati varName ili ndi mauthenga otseguka ndipo amathera ndi malemba oyandikana nawo, ndiye amatanthawuza chinthu china: zilembo zisanayambe kutsegulidwa ndi dzina la mndandanda, ndipo malemba omwe ali pakati pa makolowa ndi ndondomeko mwadongosolo. Apo ayi varName imatanthauzira zosiyana siyana. Kawirikawiri, varName sichiyeneretsedwa (sichiphatikizapo mayina aliwonse okhala ndi mayina a mayina), ndipo dzina losiyana la dzinali likupezeka kapena linalembedwa. Ngati varName ikuphatikizapo mayina a mayina (mu dzina lalitali ngati likutanthauza chinthu chophatikiza), zosinthika pazomwe zimatchulidwa zikuwerengedwa kapena zolembedwa.
Ngati palibe ndondomeko yogwira ntchito, varName imatanthauzira kusintha kwa namespace Ngati ndondomeko ikugwira ntchito, ndiye varName imatanthawuza kusintha kwapadera kapena komweko pokhapokha ngati lamulo lapadziko lonse likuyitanitsidwa kuti adziwe varName kuti akhale padziko lonse lapansi, kapena pokhapokha ngati pali lamulo loyitanidwa kuti lidziwitse varName kuti likhale lotanthauzira mayina.
