As the title says.!
C language can conveniently read a 2D array, but how to implement it with VBS and JS?

It seems that VBS all have functions to read a line, readline, read. Does it have a function to directly specify the character in the nth line and nth column of the file?
For JS, similar to C, does it have such a ready-made function?

In VBS, you can easily achieve reading specified content of a file by using the skipline method, readline method of the Scripting.FileSystemObject object and the Mid function:

Function GetStr(strFile,intRow,intCol) With CreateObject("Scripting.FileSystemObject").OpenTextFile(strFile) For i = 1 To intRow - 1 .skipline Next strTmp = .readline GetStr = Mid(strTmp,intCol,1) End With End Function
For reading file content into a two-dimensional array, you can use ADO to implement.

Thanks.. But the above code doesn't do the judgment of the end of the file. Currently, the key problem I encounter is that VBS judges the end-of-line character of a file. In this way, I can judge how many lines an unknown file has. There is a AtEndOfLine for judging a line end in VBS, but I can't find the function for judging the end of the file. Please help... Thanks in advance.!!!!!!!!!!!
