Is anyone actually using the base64decode from RPG and it's working?
Honestly the IBM doc is no help and my other research isn't bring up anything of a working example.

I have the response json if anyone wants it to play with.
It's just a test label.

I get the same result in the SQL tool on V7R5.
Looks like the function systools.base64decode is returning UTF8 data but does not tell SQL that the character field has a CCSID.
So, its returned without a CCSID. 65535.
When I pass the result through hex it returns the 1208 hex values for the string.
HEX( systools.base64decode(…) )
On V7R5, when using just “values BASE64_DECODE(..)”, I’m getting back a BLOB that is appears to be the value UTF8 data as well.
I can’t even pass the value through interpret() to cast it to 1208 because the length is variable.
The only way I can get this to work in RPG is to use CCSID(*HEX) for the receiver variable.
Dcl-s Var1 Varchar(4096) CCSID(1208);
Dcl-s Var2 Varchar(4096) CCSID(1208);
Dcl-s Var3 Varchar(4096) CCSID(*HEX);
Var2 = 'aHR0cHM6Ly93d3cuaWJtLmNvbS9kb2Nz+
L2VuL2kvNy41P3RvcGljPW92ZXJ2aWV3+
LWJhc2U2NGRlY29kZS1zY2FsYXItZnVu+
Y3Rpb24=';
Exec Sql set :var1 = systools.base64decode(:Var2); // SQLSTATE = '57017'
// SQL0332 Character conversion between CCSID 65535 and CCSID 1208 not valid.
Var2 = 'aHR0cHM6Ly93d3cuaWJtLmNvbS9kb2Nz+
L2VuL2kvNy41P3RvcGljPW92ZXJ2aWV3+
LWJhc2U2NGRlY29kZS1zY2FsYXItZnVu+
Y3Rpb24=';
Exec Sql set :Var3 = systools.base64decode(:Var2);
Var2 = 'aHR0cHM6Ly93d3cuaWJtLmNvbS9kb2Nz+
L2VuL2kvNy41P3RvcGljPWZ1bmN0aW9u+
cy1iYXNlNjQtZGVjb2Rl';
Exec Sql set :var1 = base64_decode(:Var2); //SQLSTATE 42806
//SQL0303 Variable VAR1 not compatible or value too long.
Var2 = 'aHR0cHM6Ly93d3cuaWJtLmNvbS9kb2Nz+
L2VuL2kvNy41P3RvcGljPWZ1bmN0aW9u+
cy1iYXNlNjQtZGVjb2Rl';
Exec Sql set :Var3 = BASE64_DECODE(:Var2);

Weird, I base64 encode a string using base64 in PASE or Linux and then pass
it to systools.base64decode() and I get garbage back.
I wondered if the garbage was EBCDIC, but I tried converting it and no go.
Wonder what's happening here?
