Hello,

like the topic says: How can I code IF ELSE ENDIF statement?

symbol_def_if %= symbol_def_if_inner;
symbol_def_if_inner %=
   (symbol_if > symbol_expr > lit("==") > symbol_expr >> symbol_else >   
symbol_endif ) |
   (symbol_if > symbol_expr > lit("==") > symbol_expr >> symbol_else >> 
*symbol_def_stmts > symbol_endif ) |
   (symbol_if > symbol_expr > lit("==") > symbol_expr >>                
*symbol_def_stmts > symbol_endif ) |
   (symbol_if > symbol_expr > lit("==") > symbol_expr
   >> *symbol_def_stmts >> symbol_else
   >> *symbol_def_stmts >  symbol_endif )
   ;


TIA

Jens
