6.9.3.1 The default value of TotalWidth for integer-type is implementation-defined.
In other words, when writing integer values to text files, the default width of the output field is implementation-defined.
Irie Pascal uses 8 as the default value of TotalWidth for integer type.
So for example
write('one=',1)
will cause
one= 1
to be written (i.e. the integer value 1 is written as seven spaces and a 1).
