Fortran添加多行注释

原文地址：http://blog.sina.com.cn/s/blog_4d3905b40100b3vq.html

做法：

在..Microsoft VisualStudioCommonMSDEV98MACROS文件夹下生成文件GrpComment.dsm

用文本编辑器打开该文件，将以下所附的代码贴在其中，保存（注意保留.dsm后缀）

启动CVF，选Tools=>Customize=>Add-insand Macro Files

在GrpComment前打勾，去掉其他的勾

在同一对话框中选Commands=>Macros，此时在右边可以看见CommentDel和CommentOut

选中CommentOut，拖到CVF的工具栏上去（添加工具钮），会弹出Button Appearance对话框

选Image and text，在下边Buttontext框中输入名称（默认是CommentOut），如“加注释”

类似的方法再将CommentDel命令以工具钮的形式添加到工具栏上，名称可取为“去注释”

这时，工具栏上应该多了两个工具钮：“加注释”和“去注释”。

用法：

加注释：选择要加注释的多行代码，点击“加注释”按钮即可；

去注释：选择已经注释的多行代码，点击“去注释”按钮即可。

适用：

后缀为f90或f77的代码文件，根据编译器默认的文件后缀不同，自行修改（f90为.f90,f77为.f）。

VBscript代码：

“`VB

Function FileType (ByVal doc)
ext= doc.Name
FileType= 0
pos= Instr(ext, ".")
ifpos > 0 then
DoWhile pos <> 1
ext= Mid(ext, pos, Len(ext) - pos + 1)
pos= Instr(ext, ".")
Loop
ext= LCase(ext)
endif
Ifext = ".f90" Then
FileType= 8
ElseIfext = ".f" Then
FileType= 9
Else
FileType= 0
EndIf
End Function
