Re: How to find whether something is changed in dspf

What I have done is:
-define define dataStructure1 with only the fields I care about.
-define dataFMT01 like dataStructure1.
-before the exfmt: "dataFMT01 = dataStructure1;"
-after the exfmt: "if dataStructure1 <> dataFMT01;"

Like this:
D dataStructure1 ds
D FIELD1
D FIELD2
D FIELD3
D FIELD4
D dataFMT01 s like(dataStructure1)
...
dataFMT01 = dataStructure1;
exfmt FMT01;
if dataStructure1 = dataFMT01;
exsr updateFile;
endif;
....
