The first quick question regards 'On error resume next'. In the docs
it says that this should appear if every called function if the script
is to totally resume on error. Would or should I make the 2 additions
to my current scripts marked by '>' ?

Work with very simplistic samples until you grok the err scoping behavior
:-).

On Error Resume Next
'errors are trapped locally

wscript.echo "before SubA"
Call SubA()
wscript.echo "Err after SubA", err.number, err.description, err.source

Err.clear

wscript.echo "before SubB"
Call SubB()
wscript.echo "Err after SubB", err.number, err.description, err.source

Sub SubA()
'no local errors trapped here!
Err.Raise &hff, "SubAError", "SubA"
wscript.echo "Err in SubA", err.number, err.description, err.source
End Sub

Sub SubB()
'local errors are trapped here!
On Error Resume Next
Err.Raise &hff, "SubBError", "SubB"
wscript.echo "Err in SubB", err.number, err.description, err.source
Err.clear
End Sub

So, if I really don't care if he script kicks out an error, I should
put On Error Resume Next statements in my functions?- Hide quoted text -

- Show quoted text -

So in...

Sub SubB()
'local errors are trapped here!
On Error Resume Next
Err.Raise &hff, "SubBError", "SubB"
wscript.echo "Err in SubB", err.number, err.description,
err.source
Err.clear
End Sub

execution will continue, but in SubA() it will not?
