It is more efficient to skip the function invocation and use the predefined string constants rather than calling Chr$() or
ChrW$() for the following numbers:
- 0 -
vbNullChar
- 8 -
vbBack
- 9 -
vbTab
- 10 -
vbLf
- 11 -
vbVerticalTab
- 12 -
vbFormFeed
- 13 -
vbCr
- 13+10 -
vbCrLf | vbNewLine
- 34 -
""
Noncompliant code example
Dim myChar As Char
myChar = Chr$(0)
Compliant solution
Dim myChar As Char
myChar = vbNullChar
