Figure 1. L6 Format
L6 indicates the average number of bytes of work space each record will need, overriding (if present) the l6 parameter of the RECORD control statement. The decimal value n of the optional L6 parameter is provided by the HISTOGRM utility program. If neither L6 nor l6 is provided, MFX will estimate this value.
L6 is only used for sorting variable-length records. It is ignored by merge, and copy applications.
