SYMPTOMS
The ASCAN function may sometimes fail to find an integer value that is present in the searched array when values within the searched array are changed in an iterative loop.



RESOLUTION
As a workaround, you can convert a value in the scanned array to a character string, then back to a numeric data type, before issuing the ASCAN function. laarraysearched[1] = STR(laarraysearched[1]) laarraysearched[1] = INT(VAL(laarraysearched[1])) This must be done in two separate program lines, not all in a single line as in the following: laarraysearched[1] = INT(VAL(STR(laarraysearched[1])))



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem has been fixed in Visual FoxPro 5.0a.



MORE INFORMATION
The ASCAN function should return an element number if the value scanned for is contained in the scanned array. Under specific circumstances, ASCAN may return a 0 (that is, the value is not found) when seeking an integer value if the searched array has been repeatedly repopulated within an iterative loop. Under these circumstances, ASCAN functions properly in Visual FoxPro 3.0b.
