I remember being a kid in the 1980s and numbering lines in BASIC because you had to. Nowadays, as far as I knew, numbered lines were 100% out; no one wants or needs to use them. That's until I discovered some legacy code I needed to work on. Every function has its lines numbered in increments of 10. My question is, are there any negative ramifications to using a mix of numbered and unnumbered lines? For example, if I'm modifying a function, can I just remove all the numbering from that function only without having any problems? I really don't feel like trying to maintain such an arcane system if I don't need to, but I also don't think there's any major benefit to clearing out all the numbering for the entire project.
To the best of my knowledge, line numbers in VB6 are only helpful for error handling. Something like this:
Private Sub Command1_Click()
Dim i As Long
On Error GoTo ErrorHandler
10: i = 20
20: i = i / 2
30: i = i / 0
Exit Sub
ErrorHandler:
MsgBox ("Error on line: " & Erl)
End Sub
When you run this code, it will say "Error on line 30". There is a free tool for VB6 called MZ Tools that is a plug in for VB6. This tool can add/remove line numbers as well as insert error handling for you. I encourage you to take a look at it.
