This function returns the number of times one string occurs in another. For example:
«CountOf('.', IPAddress)»
will count the number of times the character ‘.’ (full-stop or period) occurs in the data element IPAddress (and put the result into the merged document).
A more typical use of the function would be as part of a conditional statement, for example:
«If(CountOf('.',Name) < 1)»The name contains no initials.«End()»
