Hi Scott, You need to initialise Y to null at the start too.
Y = "" Regards, Jeff Marcos -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Scott Ballinger Sent: Tuesday, 11 September 2007 11:35 AM To: u2-users@listserver.u2ug.org; Dana Moore Subject: [U2] UV basic assignment error ? Here is a weird UV error condition that I just spent way too long debugging: >CT BP SB SB 0001 X = "" 0002 IF X EQ "" THEN X = Y 0003 PRINT "ONE" 0004 PRINT "TWO" 0005 PRINT "THREE" 0006 PRINT X 0007 Y = "A" >RUN BP SB ONE TWO THREE Program "SB": Line 6, Variable "X" previously undefined. Empty string used. Why does the run-time error happen in line 6 instead of line 2? This is _not_ what I was expecting. In D3: :run bp sb [B10] in program "sb", Line 2: Variable has not been assigned a value; zero used. ONE TWO THREE 0 I like the way D3 reports this better. Is this a normal, known UV thing? Perhaps this is just the first time I have ever tripped over it... /Scott Ballinger Pareto Corporation Edmonds WA USA 206 713 6006 ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
