Hi, the manual states:
DYNSPC=ntemporarily overrides the DYNSPC installation option, which specifies the total default primary space allocation for all of the dynamically allocated work data sets when the input file size is unknown. That is, when DFSORT cannot determine the input file size for a sort application and the number of records is not supplied by a FILSZ or SIZE value. Generally, DFSORT can automatically determine the input file size. However, in a few cases, such as when an E15 supplies all of the input records, when information about a tape data set is not available from a tape management system, or when Blockset is not selected, DFSORT cannot determine an accurate file size. In these cases, if the number of records is not supplied by the FILSZ or SIZE run-time option, and dynamic allocation of work data sets is used, DFSORT uses the DYNSPC value in effect as the approximate amount of primary space. DFSORT uses 20% of the primary space as secondary space. Although the primary space is always allocated, secondary space (up to 15 extents) is only allocated as needed. It seems DFSORT does calculate the size of SORTWKxx if DYNALLOC is in effect. Regards.
