1536 <para> Normally, LWASM makes a distinction between PC and PCR in program
1537 counter relative addressing. In particular, the use of PC means an absolute
1538 offset from PC while PCR causes the assembler to calculate the offset to the
1539 specified operand and use that as the offset from PC. By setting this
1540 pragma, you can have PC treated the same as PCR. </para>
