Does Layer Map implicitly OR all sublayers into specified Layer?

Hi,

 

I have a statement like this in my calibre DRC tvf file:

 

LAYER SRAM_OUTLINE 65001

LAYER MAP 123 DATATYPE < 65000 65001

LAYER MAP 124 DATATYPE < 65000 65001

LAYER MAP 125 DATATYPE < 65000 65001

LAYER MAP 126 DATATYPE < 65000 65001

 

From the documentation it appears that, the above statement will have the same effect as doing an OR of 123 , 124,125, 126 and putting all the polygons in a single layer 65001. Is my understanding correct?

 

I have another OR statement:

 

thin_lines = OR SRAM_OUTLINE SRAM_OUTLINE SRAM_OUTLINE SRAM_OUTLINE

 

Calibre issues error on the above statement:

ERROR: Error INP5 on line 57 of SVRF generated from TVF - identical input layers for this operation: or.

 

I understand doing on OR on same layers is redundant, but why an error. Is there a way to convert the above ERROR to warning in calibre?

 

Thanks
