SystemConfiguration() can return the data record length limit that triggers an increase in the size of the log files. Transaction controlled records longer than this limit increase the size of the log files or cause a TLNG_ERR (654) if the log space is fixed. cfgLOG_RECORD_LIMIT is the index into the array of LONGs filled in by SystemConfiguration(). The initial record length limit is approximately one fortieth, 1/40, of the total log space. The limit is reset each time the log size is adjusted.
