问一个程序的编译问题
程序代码:
[local]1[/local] assume cs:codesg,ds:data,es:table data segment db '1975','1976','1977','1978','1979','1980','1981','1982','1983' db '1984','1985','1986','1987','1988','1989','1990','1991','1992' db '1993','1994','1995' dd 16,22,382,1356,2390,8000,16000,24486,50065,97479,140417,197514 dd 345980,590827,803530,1183000,1843000,2759000,3753000,4649000,5937000 dw 3,7,9,13,28,38,130,220,476,778,1001,1442,2258,2793,4037,5635,8226 dw 11542,14430,15257,17800 data ends table segment db 21 dup ('year summ ne ??
