ADJVMAXRECSZ Parameter

To support IBM and other vendor changes, CA Compress by default no longer assumes that the compressed VSAM maximum RECORDSIZE is 8 bytes greater than the real uncompressed maximum RECORDSIZE. This adjustment is made only if the maximum is exactly eight more than the specified average, in which case CA Compress assumes it was originally fixed length with the maximum equal to the average. If you have applications that always expect CA Compress to make this adjustment as in the past, you may need to specify ADJVMAXRECSZ to satisfy them. This is a conversion aid until you fix all such applications. Making this adjustment when it should not happen may cause problems with other applications
