RE: Using %Dec and %Int instead of atoi

Yes,
%INT() will blow up if the string is empty/blank.
atoi() will return zero.

I prefer atoll() for longer values and tend to use it exclusively (instead of
atoi()).

%INT() accept strings with embedded blanks, such as "1 2 3", and return 123.
atoi() will not return 123.

%DEC and atoi() are not really a fair comparison. One does packed decimal
output, the other does integers which can be easily copied to packed decimal.

%DEC() uses hard-coded length and decimal positions.
atoi() doesn't use a length.

Subject: Using %Dec and %Int instead of atoi

Hi list,

 

Until yesterday, we still had 1 client under V5R1M0.  Finally he moved
to V5R3M0, so now we don't have to compile our programs to target
release V5R1M0.

 

Until now, we used the C-function "atoi" to convert character fields to
numeric, because %Int and %Dec couldn't be used for V5R1M0.

Are there any disadvantages (or benefits) in the use of %Int and %Dec
instead of atoi ?
