Return statement Usage

parvathi · Post by **parvathi** » Wed Apr 11, 2007 3:03 am

I have used a code snippet like this:

Equate TransformName To "rtnXmlChange" 

VarCount = DCount(InitialValue,',')
For i=1 To 2

GoTo Read

Next i

Read:
OpenSeq SourceFile To SrcFileVar
   On Error Call DSLogFatal('Error ' , TransformName ) 
   Locked Call DSLogFatal('Locked ' , TransformName )
Else Call DSLogFatal('Cannot open ' , TransformName ) 

Loop 
While ReadSeq Record From SrcFileVar
NewData=NewData: Char(10) :Record
Repeat

CloseSeq SrcFileVar
Return


Ans = New_Data

I am getting the following warning:

Compiling: Source = 'DSU_BP/DSU.rtnXmlChange', Object = 'DSU_BP.O/DSU.rtnXmlChange'
******?
0054 Return
^
WARNING: no RETURN value specified, null used.

0069 Return
^
WARNING: no RETURN value specified, null used.

Compilation Complete.

I would be happy if you can respond to this as soon as possible.
Thanks in advance

Check your spelling

NewData and NEW_DATA is not the same

Change your first post with the actual spelling, please.

I suspect you meant GoSub not GoTo. But there's more problems than that.

Delete the line with "Return"

Return is a valid statement. It will always give you a warning. It causes all kinds of problems. Try to avoid it. If you want to know how to use it then let us know.

You're in a transformation function. That is your Routine type. I can tell because you are setting a value for Ans.

In a transformation function you must use the Return() function (with a value), not the Return statement (which is used in internal subroutines in before/after subroutines).

You might also ask yourself what happens when your code steps past the Next statement. And what happens the first time the assignment to New_Data is attempted, with New_Data never having been assigned a value.

Why are you opening the same file twice? (You could use Seek statement to reposition to beginning of file.) Why are you reading the same file twice? Wolfgang has already alluded to the fact that variable names are case sensitive.
