No come th phon call an letters A first though tha peopl wer askin fo hel bringin u N-COM I wa no lon tha realize tha the wer ver successfu gettin N-CO running Thei mai questio wa "Wha d d wit it no tha i i running?" thin th proble i tha man user di no reall tr t exercis CP/ o pus i t it limits The neve experience th feelin o CP/ fightin bac a you The neve reall understoo th limitation o CP/ s the don' no understan ho N-CO i muc better Man use thei CP/ system t onl ru application suc a wor processor an spreadsheets Man neve ra har disk an man never eve use use are othe tha zero (Mos stil don' kno wha use are i today.) I thi article wil approac N-CO fro th ne use standpoin an answe man o th commo question aske b th ne users wil compar som o th N-CO feature t plai CP/ t hel yo understan th similaritie a wel a th differences. hav hear i sai man time tha th wa t lear ZCPR o th man associate environment (-SYSTEM N-CO etc wa t firs rea th documentation The rea th documentatio again Finally rea th documentatio thir time -Syste i s comprehensiv tha i i almos impossibl t lear everythin abou it Som o th materia wil presen her i rehas o th sam thing presente before However a slantin thi articl mor towar th beginne a wel a spendin mor tim contrastin N-CO feature wit tha o plai CP/M.
