RE: Converting string containing packed decimal to numeric decimal

Is there any references in IBM manuals to cvthc?  I've checked the ILE C
for AS/400 Run-Time Reference but can't find it.  I know that it's in
the QC2UTIL1 service program.

I was trying to use QXXPTOI but that only returns integer values.  I
need this to return values whose size and decimal positions is only
known at runtime.
