I'm using a MAX32664/MAXMAX30101 with 18F4550

This boards requires changing the direction of a pin from OUTPUT to INPUT during the program.

Can GCB support this? If so how.

Yes, just use dir port.pin In|Out

I would use an alias for port.pin.

But, this is a common practice.

I have this in my code:

define MFIO_Pin PortA.4

dir PortA.4 In|Out

When I compile I get this error message:

Oximeter_5.gcb (68): Error: Invalid pin direction, expected In or Out
Oximeter_5.gcb (68): Error: Syntax Error

Did I do what you suggested, correctly?

In|Out means In or Out. You cannot use In|Out

I tried dir PortA.4 In OR Out but
got the same error message.

Dir port.pin In

or on another line

Dir port.pin Out
