The interesting thing under 3.62 is if you init the variable at the beginning, as with:

$chk = ""

then it's null at the end.

If you change J's code at the end as follows:

? "NAV is " + $CHK

then it doesn't return a "0"

The real problem in J's code is with his first Select - Case group. He forgot the third possibility, that it is neither. One should always include a dummy Case, well, just in case (pardon the pun) none of the anticipated return true.

So, with Jochen's permission, I would like to amend a section of code as follows:

code:

---

IF @error = 0
    $x = READLINE(1)
    IF $x
        DO
            SELECT
                CASE instr($x,"rtvscan.exe")
			$CHK = "NAVNT"
		CASE instr($x,"rtvscn95.exe")
			$CHK = "NAV9X"
		CASE 1
			$CHK = "Neither"
	   ENDSELECT
            $x = READLINE(1)
        UNTIL @error
    ENDIF
ENDIF

---
