Hi Troy, I thought it might be a memory issue but it seems to be data. It will happen on the first loop if I restrict the pointer to a record that causes the problem but I can not determine why the same variable condition with data from that record will evaluate as False at one point and True a few lines later ... can memory leak show up on the second pass of a while loop? I will try switching to a go to and let you know ... at this point I will try anything ...
:-} Thanks for the tip, Michael Moser EXAQ Micro Services Phone: 916-768-7656 Fax: 916-966-8313 >> This is probably a memory leak issue related to a while loop. >> Try changing your while loop into an IF statement and a GOTO. >> Troy >> -----Original Message----- >> From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Michael >> Moser >> Sent: Monday, August 18, 2003 9:46 AM >> To: RBASE-L Mailing List >> Subject: [RBASE-L] - The impossible seems to happen >> Hi all, >> Here is a mystery that I have been beating my head against a wall with. >> This code processes about 8,000 records just fine then, with about 2,000 >> records to go, goes into a infinite loop where variables have to have the >> same value but do not. if I reverse the sort order, the problem happens >> after about 300 records. >> P800, 512MB Ram, Windows XP Pro, R:Base 6.5++ 1.864xRT03. >> Suddenly the second while loop starts evaluating as False, even though the >> values are being set immediately above it to insure a True evaluation.
