Depends what you mean. If you mean that you want to convert the decimal digits 0, 1, ..., 9 to their ASCII values, then you simply need to add 0x30 (or 48 in decimal) to it.

So, the character '0' has ASCII value 48, '1' is 49, etc. ... until '9' which has 57 as ASCII value.

Your question is a little vague. How do you intend to use this "conversion" formula?

al3457:

Normally, I would expect that this question involves a network-transport such as FTP where the "decimal" value is a packed-decimal field. The transport function has sent records from the file. The file has EBCDIC encoding on the sending side and ASCII on the receiving side. The transport then applies EBCDIC-to-ASCII translation on the entire record as a single string; this causes packed-decimal fields to be improperly translated as characters rather than as the half-bytes (nibbles) that make up the "BCD" portion of EBCDIC.

Under those circumstances, the ASCII translation to 'fix' the fields must take into account the particular conversion tables that were used in the network transport. A straight character conversion will not work.

So, the question requires some added clarification.

Please describe the circumstances. What platform will be running the conversion? Is this running on an ASCII or EBCDIC system? What does the data look like -- is it records in a file? fields in records in a file? single values passed in as parms? What languages are to be used?

Perhaps most importantly, is it really a conversion that's needed? Or would it be better to fix the problem that caused packed-decimal values to arrive on an ASCII system?

Hi al3457,

Are you aware that FTPing from the AS/400 or using ODBC, is automatically converting fields from EBCDIC-to-ASCII, no conversion needed.
Just a remark :)
