主题：强烈建议恢复eval 六步曲的原帖子呀。

Eval可能是易表的精髓函数。看了很多都看不懂，记得当时看六部曲的帖子一下就看懂了。

但现在找不到了。

哪位大侠能恢复一下。

 

写Eval公式『六步曲』

左拼部分 + 用Substitute把分隔符替换部分(中间) + 右凑部分

1、       写出列表集（此较为关键）：

[%JC%]=ListFor("客户档案","简称",1)

[%JC%]→一翻二

Eval("Substitute(""|@|"",""|"","""+Substitute([%JC%],"|",""")+""|""+Substitute(""|@|"",""|"",""")+""")")

2、写出最简单的循环命令。

  ReplaceFor(Grid,"简称","A","进货单位","Instr","A") And ReplaceFor(Grid,"简称","B","进货单位","Instr","B")

3、把第2的命令粘贴到记事本中：

编辑→查找替换→在查找框输入：『"』→在在查找框输入：『""』→全部替换，得到 (此时列表为：A@A|B@B)

ReplaceFor(Grid,""简称"",""A"",""进货单位"",""Instr"",""A

(左拼部分)        (A)  (A@A及B@B間的“@”)    (A)

"") And ReplaceFor(Grid,""简称"",""B"",""进货单位"",""Instr"",""B"")

右凑部分

(A|B間的“|”)        （B）

4、用Substitute把第1的列表集中的分隔符“@”和“|”分別替换为 第3点字符集中的红色部分『"",""进货单位"",""Instr"",""』，和粉紅色部分『"") And ReplaceFor(Grid,""简称"",""』，

得到中间部分:

  Substitute(Substitute(Eval("Substitute(""|@|"",""|"","""+Substitute([%JC%],"|",""")+""|""+Substitute(""|@|"",""|"",""")+""")")

,"@"," "",""进货单位"",""Instr"",""")，"|"，""") And ReplaceFor(Grid,""简称"",""")

5、加上『左拼部分』（第3中列表第一个字符前面所有字符）和『右凑部分』（第3中列表最后字符后面所有字符）

" ReplaceFor(Grid,""简称"","""+Substitute(Substitute(Eval("Substitute(""|@|"",""|"","""+Substitute([%JC%],"|",""")+""|""+Substitute(""|@|"",""|"",""")+""")")

,"@"," "",""进货单位"",""Instr"",""")，"|"，""") And ReplaceFor(Grid,""简称"",""")

+""")"

6、最后用Eval执行它，OK！

Eval(" ReplaceFor(Grid,""简称"","""+Substitute(Substitute(Eval("Substitute(""|@|"",""|"","""+Substitute([%JC%],"|",""")+""|""+Substitute(""|@|"",""|"",""")+""")")

,"@"," "",""进货单位"",""Instr"",""")，"|"，""") And ReplaceFor(Grid,""简称"",""")

+""")")

原贴不知道还能不能恢复？！再发一个参考！
