Re: How to convert ascii value to hex in RPGLE

Rishi,
For a better understanding of CCSIDs and ASCII vs. EBCDIC vs. Unicode,
please look at this:
http://www.databorough.com/downloads/modules/unicode.pdf

This is a short presentation with sample code in RPG IV, COBOL and CL
included.

It even shows how to use the "iconv()" API.

*i got below error when i tried to use this sql to get hex value.*




Message . . . . : The target for a numeric operation is too small to
hold
the result (C G D F).

Cause . . . . . : RPG procedure SQ8 in program RISHI/SQ8 at statement
152
performed an arithmetic operation which resulted in a value that is too

large to fit in the target. If this is a numeric expression, the
overflow
could be the result of the calculation of some intermediate result.

Thanks much..

I know this is the rpg forum but...
Would it be too terrible to suggest letting sql do it?
Doesn’t this convert to hex?

Select hex(myField)
Into :myHostvar
From sysibm.sysdummy1

SInce your file will have very little records, you can store as 2

this is what I wrote a few days ok. Source can be any size.

dcl-pr ConvertToHex ExtProc('cvthc');
PR_HexValue Pointer Value;
PR_CharValue Pointer Value;
PR_SourceLength Int(10) Value;
end-pr;

dcl-ds ldsCharUnsigned Qualified;
Value Uns(10);
end-ds;

dcl-s lHexValue Char(8);

ConvertToHex(%Addr(lHexValue):%Addr(ldsCharUnsigned):%Size(lHexValue));

Because it is passing a pointer, the length can be anything. Just

make

sure

that lhexvalue is twice as long as what you are converting.

They should really be more flexible than that. This is basically

what I

have:

Dcl-Pr ToHex EXTPROC('cvthc');
HexResult Char(65534) OPTIONS(*VARSIZE);
CharInp Char(32767) OPTIONS(*VARSIZE);
CharNibbles Int(10) VALUE;
End-Pr;

Dcl-Pr FromHex EXTPROC('cvtch');
CharResult Char(32767) OPTIONS(*VARSIZE);
HexInp Char(65534) OPTIONS(*VARSIZE);
HexLen Int(10) VALUE;
End-Pr;

Call a MI:

Shouldn't one of those first two parms in the prototype
