First I apologize for the lame "reply" format - I am forced to use Microsoft Outlook Web Access (shudder) at work and wouldn't you know - it doesn't offer any options for mail format...? > Based on your rules above, TALL0047A and TAL0047A do in fact match
No, actually - however many characters are present in each have to match. If the number of alpha characters in the first set of each field in the two lists differ - no match. > Are you really saying: > From both items > remove trailing alphas No. If trailing alphas are present they must also match. > take the last 4 digits > remove any leading zeros Yes. > Do the strings always start with alphas?

Yes - always start with alphas. >Is there stuff between the leading and ending portions, such that the > entries may be more than 10 characters long? There will never be more than 4 leading alphas, 5 numerics, and 2 trailing alphas. ________________________________ From: [EMAIL PROTECTED] on behalf of Jay Strauss Sent: Fri 7/8/2005 8:49 AM To: lugod's technical discussion forum Subject: Re: [vox-tech] Matching Contents of Lists > > Examples of matching: > > TALL0047A TALL047A match > TALL0047A TAL0047A not a match > TALL0047A TAL0470A not a match > > > The contents will always be one to four alpha characters followed by one > to four numeric characters possibly followed by one or two alpha > characters. > > A match would be defined as the following criteria being met: > > - The last one to four digits being identical (excluding leading zeroes) > - The first one to four letters being identical I think your rules need more flushing out because based on your rules you can get many entries in list 1 to match a single entry in list 2 > TALL0047A TALL047A match > TALL0047A TAL0047A not a match Based on your rules above, TALL0047A and TAL0047A do in fact match Are you really saying: From both items remove trailing alphas take the last 4 digits remove any leading zeros if the remaining digits match from both items move on to the front of the string if the leading alphas match (i.e. have the same length and same sequence) then you have a full match Do the strings always start with alphas? Or are there sometimes numerics within the first 1-4 characters? Is there stuff between the leading and ending portions, such that the entries may be more than 10 characters long?
