Issue:
A NCL to read a file by $DSCALL OPT=READ.

When it reads the file having 10800 records, it takes CPU time 30s. Why does $DSCALL OPT=READ use so many CPU time ?
Resolution:
Using $DSCALL DATA=* for the READ of the file is a lot more efficient, but does limit the reading of the file to the 1st 9,999 records, but this will save a lot of CPUTIME if the process can be adjusted to limit the input file size.
