Syntax: @STRLEN(argumentlist)
argumentlist = any combination of numbers, cells, or ranges
@STRLEN returns the total length of all the strings in its argument list. It differs from @LENGTH in that it can take multiple arguments, but more significantly, it returns the length of the formatted contents of a cell, even if it contains a numeric argument.
Example:
@STRLEN(``PHYSICS'') = 7
@STRLEN(B1) = 34, where B1 = ``Engineering Scientific Spreadsheet''
@STRLEN(A1) = 10, where A1 contains the value formatted as currency with two decimal places so that it appears on screen as $1,000.00 (plus a trailing blank).
