Answer Posted / pravin
clear and reset both opcodes are used for clearing the
fields and then initialise the numeric fields with
zero and character with blanks difference is that if we
define any initilialise value for that var in pgm reset
initialize it by that value but clear initialize it by zero
or blanks.
OPEN & CLOSE opcodes are used for explicitly open and
close the file.
SFLNXTCHG :Its always read those records which changed
in uppdatesubfile.this is declared in subfile(SFL) format
not
SUBCTL format.
