Code: Select all

Result = CountString(String$, StringToCount$)

eg

Code: Select all

Char90Count = CountString(Source, chr(90))

EDIT:

Finding:

Code: Select all

Position = FindString(String$, StringToFind$, StartPosition)

This is in the String section of the help docs.

Hope that is what you were after.
