Shift Function gives MPASM error

[blackwood]

I have a PIC18F2520 project which uses shift operators.

e.g. B1 = B1 << 5
(B1 is a byte variable)

When it compiles, MPASM produces the following error result:

ERROR[126] f:\pbp26\pbppic18.lib 662: Argument out of range (16388 not between 0 and 16383)

If I comment out the shift function, the project compiles/assembles without error. Any shift function produces a similar error.

I have to use MPASM so how can I perform a shift function.

I am using PBP2.6a and MPASM v5.37.

It would help if you would show your whole code.
What is the value of B1?

[blackwood]

The value of B1 does not seem to affect the error message. I have tried forcing B1 to 1, 40 and 255 and the error message is the same.

This compiles fine here

 
B1  var BYTE 
B1 = 255
B1 = B1 << 5

So the problem is someplace else.

[blackwood]

I have just found that if I comment out the following include files, the shift function in the main program compiles/assembles without error.

With the shift function omitted and these files included, the program compiles/assembles without error and runs perfectly so somehow one of them is affecting MPASM and shift functions.

'INCLUDE "DT_INTS-18.bas"
'INCLUDE "ReEnterPBP-18.bas"
'INCLUDE "NewRXbuff.inc"

What is
'INCLUDE "NewRXbuff.inc"

The other two if unchanged are good files.
