displaying #v as hex value in MPASM

displaying #v as hex value in MPASM

PIC forum current not letting me post so will try here. I am writing a dim macro to overcome issues such as 151 errors and to keep track of array sizes (I will probably add some 'typing' at a later stage such as int, uint int16 etc). Below is an example of filling up some memory and the macro. I am using #v to display the allocated memory locations for the enhanced 14-bit core PICs. I'm pretty sure I have it debugged, but it would be much much easier if the memory locations were displayed in hex. I can probably write a dec to hex macro, but it may already have been done. Has anyone written such a macro - most search tools make it very difficult to search for #v so I apologise in advance if this is a simple task.
