1. a little confused about scope
Hi all,
I was having trouble figuring out why I get an error in my program if I
declare a variable in the middle of a procedure as opposed to declaring
it at the top of the procedure. If I declare it at the top of the
procedure, my program runs fine.
This generates the error message: "expected to see possibly 'end', not a
type"
But if I put the declaration at the top of the procedure it runs fine.
Do private variables in functions have to be declared before anything
else? I read the manual under scope, but I didn't come across any
hardfast rules, am I missing something?
procedure test_block_1()
position (20,1)
puts(1,"RAW INPUT:")
print (1,raw_data)
position(22,1)
print(1,process_one)
position(23,1)
puts (1,"LENGTH OF COMMONWORDS SEQUENCE: ")
print(1,length(common_100))
position(27,1)
puts(1,"LENGTH OF TOKENIZED DATA: ")
print(1,length(process_one))
object x <<<<<<<<<<<<<<<<<OFFENDING LINE<<<<<<<<<<
position(28,1)
x=find("in",common_100)
puts(1,"WHICH PLACE IN COMMONWORDS SEQUENCE: ")
print(1,x)
position(29,1)
print(1,process_two)
position(30,1)
puts(1,"WHICH PLACE IN FIRSTWORDS SEQUENCE: ")
print(1,process_three)
end procedure

I think there was something in the "refman.txt" about this.
I seen it somewere in the docs.
Yes, you must always declare variables within any routine type at the top
befor any other call.
