Procedure flag resets itself?

honoluludesktop

What am I doing wrong. I am calling a procedure "Entities_In" from another, "Block_In", but when it returns, "polyline_flag" is reset from "1" to "0". The "puts" are in the code for debugging. I verified that at the end of "Entities_In" that the flag is correct, but when it returns to where it is called from, within "Block_In", it is no longer set correctly. Is there something about passing parameters that I do not understand?

The "puts" as in the ruby console:
goto entin from blkin, plflag 0 polyline face PL_DFace_In POLYLINE return from plin, plflag 1 prior exit entin, plflag 1 return from entin, plflag 0

def Block_In(count,dface_flag,dface_option,line_off,arc_flag,circle_flag,polyline_flag,insert_flag,block_flag,line,insert_off)
	if line == "INSERT\n"
		Insert_In(count,insert_flag,insert_off,line)
		else if line == "ENDBLK\n"	
			block_flag = 0
		else
puts "goto entin from blkin, plflag "+polyline_flag.to_s
			Entities_In(count,dface_flag,dface_option,line_off,arc_flag,circle_flag,polyline_flag,insert_flag,block_flag,line)
puts "return from entin, plflag "+polyline_flag.to_s
		end
	end
end

def Entities_In(count,dface_flag,dface_option,line_off,arc_flag,circle_flag,polyline_flag,insert_flag,block_flag,line)
.
.
.
	if line_flag == 1
		Line_In(count,line_flag,line_off,line)
		else if polyline_flag == 1 and dface_option == 0
			Polyline_In(polyline_flag,line)
			else if polyline_flag == 1 and dface_option == 1
				PL_DFace_In(polyline_flag,line)
puts "return from plin, plflag "+polyline_flag.to_s
				else if circle_flag == 1
					Circle_In(count,circle_flag,line)
					else if arc_flag == 1
						Arc_In(count,arc_flag,line)
						else if dface_flag == 1
							DFace_In(count,polyline_flag,line)
						end
					end
				end
			end
		end
	end
puts "end of plin, plflag "+polyline_flag.to_s

end

I haven't looked closely at your code... BUT try to start your 'defs' with a lowercase letter NOT a CAPITAL letter ?
def blockXXX(...) NOT def **B**lockXXX(...)
Capitals are reserved for class/module and global constants etc...

Tried it, but "no can do". No caps, too bad, I used caps to make the code easier to read.

My problem reminds me of a "grade school" rule. "Pass on, no pass back"

OK, I figured out how to use instance variables by @variable. If I use them, will other plugins be affected in the manner of global variables?

I understand why not to use global variables, can the other types be problematic?

First the def's "no-CAPS" rule only applies to the first letter! So def blockXXX2(a,b,c) is fine...
Conversely a class should start with a CAP [ class BlockXXX]...
The @variable is only used in that activated instance of that class/module or group of defs.
There is a @@variable type that you can make when the class/module is first initialized.
These @ types remain within there bounds - unlike $variable which pervades all tools and can be dangerous if the name is 'common' - using $x in you tool is fatal to any other tool foolish enough to use it too - $x_my_special_tool_XXX_variable is less likely to clash!

TIG, thanks for the lesson.

" @x"'s a typo, yes. Assuming you mean "..using $x in..". Anyway I rewrote the code with @variable for those that have to be available for different procedures.

Typo fixed
[I an conditioned not to type $ in front of a variable name!!!]
