write ('There are ', items:1, ' items')

Clipping only applies to strings.

write ('You name is Phil.')    :)

In standard Pascal there are no string schema types like extended Pascal,
but in extended Pascal "write(s)" is identical to "write(s:length(s))".

"Strings" in standard Pascal are typically an "array [1 .. n] of char".
The programmer then needs to keep track of how many of the n characters
are valid.  Then the write statement would look like "write (s:sizeofs)".
