Njengomphuhlisi weCOBOL, ndiyayiqonda indlela ekubaluleke ngayo ukwaphula iingxaki ezinzima zibe ziziqwenga ezilawulekayo. Ngokunjalo, njengengcali yefashoni, ndiyakuqonda ukubaluleka kokwaphula izitayile ezintsonkothileyo kwaye ndijonge kwiindlela eziqondakalayo. Makhe siphonononge indlela “yokushicilela” kwikhowudi yeCOBOL kunye nendlela edibana ngayo nehlabathi lefashoni.
Ingxaki ngo 'Shicilela'
Kanye njengokuba ihlabathi lefashoni linobunzima balo, ngokunjalo nehlabathi lenkqubo. Umba omnye oqhelekileyo obonakalayo unxulumene neziphumo zoshicilelo kwi-COBOL. Isenokubonakala ilula, kodwa eneneni, luhlobo olukhohlisayo. Ifuna ukuqonda okufanelekileyo ngezinto ezahlukeneyo mathala eencwadi kwaye imisebenzi ukulungisa le ngxaki.
Umsebenzi obalulekileyo walo naluphi na ulwimi lwenkqubo, kubandakanywa neCOBOL, ukusebenzisana nehlabathi langaphandle. Ngokuqhelekileyo, oku kwenzeka ngojongano lwekhonsoli apho inkqubo ivelisa umbhalo kunye nokubhaliweyo kokufakwa komsebenzisi. Kubathandi befashoni, oku kufana nabaqulunqi ababonisa indalo yabo kwi umzila kunye nokufumana ingxelo evela kubaphulaphuli.
Ukuguqula ikhowudi uMsebenzi 'woShicilelo'
Umsebenzi othi "Shicilela" kwi-COBOL ufana nekhithi yezixhobo zesitayile kwifashoni. Kanye njengokuba abenzi besitayile basebenzisa uluhlu lwezixhobo ukugxininisa uyilo, abaphuhlisi basebenzisa imiyalelo eyahlukeneyo ukugxininisa ikhowudi. Omnye onjalo ngumyalelo 'kuprinta'.

BONISA “Molo, Hlabathi!”.
MISA UKUBALEKA.
Umsebenzi 'woShicilela', ufana nomyili wesitayile esongeza ukubamba kokugqibela kwimodeli phambi kokuba abethe phantsi. umzila, yongeza isiphumo sokugqibela kwikhonsoli yomsebenzisi. Kwi-COBOL, umyalelo we-DISPLAY uvelisa isicatshulwa esilula kwi-console.
Imisebenzi efanayo kwi-COBOL
Kukho eminye imisebenzi kwi-COBOL enomsebenzi ofanayo no "Shicilela". Umzekelo, ingxelo ethi "YAMKELA" ifumana idatha kumsebenzisi efana nendlela umyili ayamkela ngayo ingxelo kubaphulaphuli bakhe. Nangona zahlukile ekusebenziseni, zombini zinegalelo kuphuhliso lwenkqubo (okanye ingubo).

Apha, i-ACCEPT isetyenziselwa ukufumana igalelo lomsebenzisi kwaye emva koko, i-DISPLAY isetyenziselwa ukuyiprinta. Ifana nefashoni ephezulu, apho i-stylist inokuthi kwamkela iindlela zamva nje kwaye emva koko Bonise indalo yakhe kwi-catwalk.
Omnye umsebenzi ofanayo kodwa obalulekileyo kwi-COBOL ngu "BHALA". Ngoku nxulumanisa BHALA umsebenzi kunye nenkqubo xa umyili ezoba uyilo ephepheni, inkqubo ebaluleke kakhulu phambi kokuba eyona nkqubo yoyilo iqalise.

BHALA IREKHODI UKUSUKA KWIDATHA YAM ISIQINISO ESIngasebenziyo “Iqhosha elingasebenziyo!”.
Ngokuqonda le misebenzi isisiseko kwi-COBOL, kulula ukucinga ukuba basebenza njani ngokudibeneyo ukwenza inkqubo yempumelelo okanye, ukwenza ingqokelela yefashoni emangalisayo. Zombini ihlabathi, nangona zibonakala zahlukile, zilandela isiseko esifanayo: qhawula ingxaki, thatha amanyathelo amancinci, ubonise inkqubela phambili, wamkele impendulo, kwaye ubhale umphumo wokugqibela.
Nokuba lukhowudi okanye yifashoni, imigaqo yokusombulula iingxaki, ukusungula izinto ezintsha, kunye nokuyila ihlala ingatshintshi. Nantso ke ubuhle bayo.
