There is no trivial solution in a standard Pascal although the
resulting code will be brief.  Here is the outline.  To convert an
integer to a string you'll need a loop, which extracts the digits
from the integer.  This is achieved by using mod.  Then you convert
a digit by using chr plus ascii for 0.  To control the loop and to
extract successive digits you must div the integer until the
division produces 0.  In order for the conversion to be general, you
must also test for the sign.  It is easier to convert a non-negative
integer, and then augment the sign to the beginning of the string.
