Printing hexadecimal values is not a feature supplied by standard
Pascal, and I can't see any mention of a library function in ORCA/Pascal
to do this.
You could use the Integer Math toolset functions to convert an integer
into a hexadecimal string. (My Pascal is rusty, so excuse any syntax
errors.)
Procedure PrintHex(intValue, width : integer);
Var s : Str32;
Begin
If width <= 32 Then
Begin
Int2Hex(intValue, @s, width + 1);
Write(s);
End;
End;
I expect you will need to USE the appropriate toolset definition file,
and you might need to start up and shut down the IntMath toolset in
order to use it.
There is also a corresponding procedure called Long2Hex, and functions
Hex2Int and Hex2Long (which return an integer and long value
respectively).

ORCA/C would be more convenient, because printf() has always supported
hex data output.

Almost there :), the compiler coudn't find Str32 type so I used Orca
String type. I got trailing garbage to each hex number I print. I think
it's because Integer Math tool set conversion routines don't provide
string termination (C-style) nor lenght info (Pascal-style). The width
parameter is actually your string length in bytes so 4+1 is ok for int
and 8+1 is ok for long integers and pointers. The '+1' is space for the
string terminator of course.
Thanks for the tip,
Yves
