Summary

0001000: Separate logical record format and length from physical (falloc()) at write

Description

At write it would be usefule, that the FALLOC descripts the physical file and DSORG/RECF/RECL on the base level descript the logical file written. The parameter are the default for falloc if falloc not defined, this means that the logical DCBs are also the physical DCBs at default. So the syntax for read.record() are identical with write.record() and the falloc object are only an additional object which could define, if the logical and physical view differs.

(0001335) Falk Reichbott (administrator) 2020-09-21 09:12	This requirement is really helpful but we can not solve this backward compatible. With the best solution the FALLOC() object is a replacement of the static allocation, which describts the physical file format and the new file organization, record format and record length defines the logical format written to the physical file and if no physical definition done, then the logical will be use for the physical as default. This was the plan, but for all customers using static allocation for the physical representation and the FALLOC() object to describ the logical, this solution will not backward compatible and all these job steps needs to be adjusted, because of the behavior change of the FALLOC() object.
