Moshe,

Here is your problem: Your interrupt ends in a RETFIE but there was never a call
 to return from.

Change your

GOTO    PULSE_CHECK
to
CALL    PULSE_CHECK

and that should fix it.

Here is my latest code version A-this works, i.e gives me the test pulses on
 portA, NOTICE the parts that I have cut out (;)

                END

My code version B includes the lines;           MOVLW   B'11111111'
                                                MOVWF   TRISB
and this seems to be where the problems start. I either get pulses on all portB
 pins (flat tops with narrow long V drops to Vdd) and nothing on portA or only
 RA3 will give me any pulses out and RB is zero. At the moment it seems only to
 want to generate the former (I'm telling you sometimes I believe these things
 are really alive and someone is playing a big joke on us ).

For version C I changed the value above from 11111111 to 11110000 and I now get
 nothing from portB or portA.

I do get this message from the assembler
Message[302] C:\MOSHE\SOFTWARE\WMCS_PIC\WMPIC1C.ASM 87 : Argument out of range.
 Least significant bits used.
for the lines that I write to TRIS but I get it for portA as well and that works
 fine in version A. The assembler has a FAQ on this
WHEN I ASSEMBLE MY CODE, I GET DOZENS OF MESSAGES
ABOUT TRUNCATIONS FOR REGISTER VARIABLES IN BANK
1.

The full address is not contained in the generated machine
code.  Since it is necessary to define the variables with the full
address, you may want to mask this message using the directive
"ERRORLEVEL -302".

Thanks once again

Moshe

PS has nobody else had this problem? I'm sure it's a standard thing to read
 pulses in on portB and send out on another port.
PPS It was "feel"
