When QXE files are used to speed QAB program loading the progrun supplied with 4.520 would generally create these files with an invalid name. This problem was caused by a fault in the compiled QAB libraries, and does not affect other versions of progrun.
The fix is supplied in a 4.521 executable which requires 4.521 srv3 and trm3 to run.
Where the version affected is given as 4.5xx or 4.6xx, all versions of DP4 issued prior to the date of the fix are potentially affected. Where a specific version number is given the problem was introduced by that release and prior releases are unaffected. If a patch release number is also specified (in parentheses) , the fault was introduced at that specific patch level.
Due to limitations on available web space downloadable fixes are only available for the most commonly used environments, and may not be separately available in both 4.5xx and 4.6xx flavours. If a file you require is not available you can ask us to e-mail it to you.
