FIX: ELSEIF Syntax Error Marked on IF Line in Interpreter

SYMPTOMS

In the following program, a syntax error in the ELSEIF portion of a block IF is misleadingly marked on the IF line instead of the ELSEIF. Other errors in a block IF usually are marked on the line that contains the error. The following is a code sample:

x=0           ' 0 means false.
IF (X) THEN   ' Error misleadingly marked here when ELSEIF executed.
    PRINT "X IS TRUE"
ELSEIF ( THEN    ' But the syntax error is actually here.
    PRINT "X IS FALSE"
END IF
				

Microsoft has confirmed this to be a bug in the Microsoft Basic Interpreter version 3.00 for the Macintosh and in Microsoft QuickBasic version 1.00 (buglist1.00) for the Macintosh . This problem is corrected in QuickBasic version 1.00b (fixlist1.00b).
