first off thank you for taking a look.  appreciated.

you mean the parser (ultimately) emits code like '#if (!sphere {...})'?  that
would certainly explain the expect numeric expression message.  disclaimer first
:-): I know nothing of the POV-Ray parser or its internal "voodoo"
managing/unwinding the call stack, and (all) too little about parsing in
general.

when I look at the 'fore_call()' macro code, given that the "payload" is a
void-type macro, the '#else' branch (line 106) will be used.  I expect(ed) the
sphere to be inserted replacing line 107.  certainly, when debug is enabled, the
subsequent '#debug concat()' always displays the value it's received in line
108.  so, not knowing the parser etc, how [cw]ould the sphere code wind up in
'fore_walker1D'?


regards, jr.
