可以按需要编码分类替换


str = "abc123-DEF..99测试"
ch1 = "1234567890"
ch2 = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
ch3 = "abcdefghijklmnopqrstuvwxyz"
ch4  = 0h000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F202122232425262728292A2B2C2D2E2F3A3B3C3D3E3F405B5C5D5E5F607B7C7D7E7F
? "只有数字：",CHRTRAN(str,CHRTRAN(str,ch1,""),"")
? "只有字母：",CHRTRAN(str,CHRTRAN(str,ch2+ch3,""),"")
? "大写字母：",CHRTRAN(str,CHRTRAN(str,ch2,""),"")
? "小写字母：",CHRTRAN(str,CHRTRAN(str,ch3,""),"")
? "数字字母：",CHRTRAN(str,CHRTRAN(str,ch1+ch2+ch3,""),"")
? "汉字编码：",CHRTRAN(str,ch1+ch2+ch3+ch4,"")
? "符号编码：",CHRTRAN(str,CHRTRAN(str,ch4,""),"")
? "非符号码：",CHRTRAN(str,ch4,"")
? "字母汉字：",CHRTRAN(str,ch1+ch4,"")

版主，前三句理解，第4句没理解，请详细说明一下。谢谢！
找出数字字符      ch1 = "1234567890"
找出大写字母字符  ch2 = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
找出小写字母字符  ch3 = "abcdefghijklmnopqrstuvwxyz"
请问ch4  = 0h0001......这句是哪种类型字符？
