i bmetcoder, i've not tried compiling it, but just ad a quick scan threw your code and noticed 2 errors that could be ausing the problem

At line 169 you have this, Change Next to Next ctr

+ Code Snippet

  if wrong = 5
      sleep 50
      cls
      for ctr = 1 to 30
         sleep 50
         ink rgb(128,0,128),0
         set text font "comic sans ms"
         set text size 30
         text rnd(580), rnd(400), "You loose! It was " + hang
     next 
      goto startofprogram
   endif

Also at line 138 you have this, but every time you use the command IF, this will also cause that error as there are insufficent EndIf's

+ Code Snippet

`If the user guesses wrong, add the body part
`to the number of wrong guesses.(ie: 1st wrong
`guess will show the head)
   if found = 0 and wrong = 0
      head()
      wrong = wrong + 1
      else
      if found = 0 and wrong = 1
      body()
      wrong = wrong + 1
      else
      if found = 0 and wrong = 2
      larm()
      wrong = wrong + 1
      else
      if found = 0 and wrong = 3
      rarm()
      wrong = wrong + 1
      else
      if found = 0 and wrong = 4
      lleg()
      wrong = wrong + 1
      else
      if found = 0 and wrong = 5
      rleg()
      wrong = wrong + 1
   endif

Try this instead

+ Code Snippet

`If the user guesses wrong, add the body part
`to the number of wrong guesses.(ie: 1st wrong
`guess will show the head)
   if found = 0 and wrong = 0 : head() : wrong = wrong + 1 : else
   if found = 0 and wrong = 1 : body() : wrong = wrong + 1 : else
   if found = 0 and wrong = 2 : larm() : wrong = wrong + 1 : else
   if found = 0 and wrong = 3 : rarm() : wrong = wrong + 1 : else
   if found = 0 and wrong = 4 : lleg() : wrong = wrong + 1 : else
   if found = 0 and wrong = 5 : rleg() : wrong = wrong + 1
   endif : endif : endif : endif : endif : endif

The problem is that inside your while/endwhile loop you have several nested "if" clauses without corresponding endif statements. The reason you are getting that message is that the compiler "sees" the endwhile before it sees the expected endif statements (which of course are missing). If you consistently indented your code you would probably have noticed the error - or you are used to a language that has an elseif structure (in DBPro each "if" needs a matching "endif" unless you are using the single line if/then combination).

Here's the offending bit with the exta indenting and endif's added:

+ Code Snippet

  if found = 0 and wrong = 0
      head()
      wrong = wrong + 1
  else
      if found = 0 and wrong = 1
         body()
         wrong = wrong + 1
      else
         if found = 0 and wrong = 2
            larm()
            wrong = wrong + 1
         else
            if found = 0 and wrong = 3
               rarm()
               wrong = wrong + 1
            else
               if found = 0 and wrong = 4
                  lleg()
                  wrong = wrong + 1
               else
                  if found = 0 and wrong = 5
                     rleg()
                     wrong = wrong + 1
                  endif
               endif ` first one added
            endif ` second one
         endif ` third one
      endif `fourth one
   endif ` fifth one

The compiler now gets past that part of the code - but there are other errors in your code. You'll see them when you try to compile again. Have a close look at your use of "letter", "itemletter" and the things you compare them with. Remember that strings need to be compared with strings.

Hope this helps.

Edit MSon beat me to it.

Serves me right for being long-winded (as usual

).

ok so i asked for help with this code a few days back and got some useful help. however now my syntax error is telling me that i did not define the variable \"letter\" when it is clearly defined at the beginning of my code. and i did not have this issue before i added on the nested if statements to add the body parts per hang man. any suggestions?? or reasoning why this syntax is occuring? thanks!

I told you before to check the following:

Quote: "but there are other errors in your code. You'll see them when you try to compile again. Have a close look at your use of "letter", "itemletter" and the things you compare them with. Remember that strings need to be compared with strings"

Have you done that? Check every occurrence of those in your code and you should see the errors yourself. Here are some hints from your code:

+ Code Snippet

letter as integer

+ Code Snippet

   if used = letter

+ Code Snippet

      if used = letter(x) and x = 1

What exactly is "letter(x)" supposed to be?

So am I. Your code compiles fine. Are you sure it was a syntax error? Or was it a runtime error?

I doubt your code will run. Have another look at this line - and check the Help file:

+ Code Snippet

while file end(1)

Remember that while/endwhile loops are executed when the condition is true.
