Well of course it doesn't work!  You are reading the file into a 20-byte 
character field and 
printing it as a string of bytes.  C doesn't understand about packed data so %s 
simply attempts 
to print the character representation of the byte.  Most packed numeric data 
results in 
unprintable characters.  The C Reference manual contains examples of how to 
process an 
externally described file containing packed data.  Read the bloody thing!

Are you a student with no AS/400 knowledge or are you working for an Indian 
body shop and 
getting farmed out for projects for which you have no skill.  There seem to 
have been a lot of 
these lately.  If the former then read the manaul before asking for help,  if 
the latter then 
get some formal training.

Simon Coulter.
