cvthc not converting all values

I have been reading the archives and looking at the MI Reference manual but I just can't figure out what I'm doing wrong. I am trying to convert a 5-digit packed value into a character value. cvthc is only converting the first byte. My test value is 12345F and my results are 12, only the first byte. The manual shows an example where it is converting a 9-byte value to character with one call. I have verified that the length I am passing is 5. I also tried 6. Any thoughts on what I'm doing wrong?

This is the prototype:
d HexToChar pr ExtProc('cvthc')
d Receiver * Value
d Source * Value
d Length 10u 0

This is the function call:
HexToChar(%Addr(ReplaceString)
:NameValuePairs.dsNameValue(Ctr).Value
:NameValuePairs.dsNameValue(Ctr).ValueByteLength);

Definitions:
d ReplaceString s 64a


d dsNamesValues...
d ds Qualified Based(Dummy)
d NumberOfValues...
d 5u 0
d dsNameValue LikeDS(dsNameValue_t) Dim(1000)


d dsNameValue_t ds Qualified Based(Dummy)
d Name 32a
d DataType 3u 0
d NumericLength 3u 0
d Decimals 3u 0
d DTZFormat 3u 0
d DTSeparator 1a
d ValueByteLength...
d 10u 0
d MaxValueByteLength...
d 10u 0
d Value *
