Re: Lost in free format conversion.

Joep is on the right track - the reason for the character in the "number" is that the sign is in the first nybble of the last digit.

It is not clear why the original RPG III program converted (moved) the value to an alpha field, but it doesn't matter. Simply do what Joep says - define the incoming parameter in the RPG IV program as 5S0 and all should be good.

An alternative is to have a data structure with a 5S0 subfield and a 5A overlaid on the zoned subfield. Then in /free set the 5A subfield to the incoming parameter value and all is good.

Joep's idea should work because what is being passed is the pointer - it's a bit of a game with pointers but should work fine.

One thing - DOCUMENT THIS TECHNIQUE in the RPG IV program, so future developers have a clue!!

Arnaud,

%char will convert corectly. After that, you can use %int or %dec :

ValueAlpha = %Char(Num20dec6);
Num20dec6 = %dec(%trim(ValueAlpha):20:6);

Armand,

Why don't you just define the incoming parameter as 5S0? You say that in
the RPG III program is converted to character, but it is not: it is just
moved. So you van just receive is as it is - a zonec numeric field.

Hello,

In a RPG3 program a numeric field is converted to a character field and
passed as parameter in a call. When this parameter is received in a free
format program and the value is positive there is no problem converting

it

back to a numeric field. But when the value was negative the value in

the

character field contains a letter so I can convert it to a numeric field
with %dec, %int or %uns.

E.g.
Field1 5.0 with value -22256 and parmField1 5A.

When the value from Field1 in RPG3 is moved into parmField1 the value is
converted from -22256 to '2225O'. In this case converting it back to a
numeric field is not possible because of the letter ?O?. The result is
message RNX0105 is trown.

Can someone please help me to solve this challenge in free format.

Best Regards / Met vriendelijke groet,
Armand
