Dan, 

How about if your customer would try the following instead: 

tr "[\177-\376]" "\*" < COMSHD > COMSHD1 

The 'sed' example behaved as you indicated even on a SPARC Unix system that
I have access.

Hi -L Gang,

I have a user who is trying to use SED to do some data manipulation and is 
not getting the desired results.

The issue is incoming data from another platform that is being fed into 
MM3000.  This data occasionally has some unprintable characters, which of 
course wrecks havoc on the MM application when it is encountered.

To address this, the user, using a cygwin (unix like) environment on their 
windows pc, developed a SED script that when they test in the cgywin 
environment, works just fine, but when done on the target HP3000 (7.0 pp2) 
gets an undesirable result.

The script below is meant to scan and substitute based on what you see 
below:

sed -e 's/[\x7F-\xFE]/*/g' < COMSHD > COMSHD1  works on cygwin

Unfortunately, while meant to catch the ascii table entry for the Delete 
Character and then subsequent unprintable characters after that (hex 7F 
thru hex FE), is in fact catching more than desired.  Below is an example 
of what is being changed that was not intended:

SI28772      JACT1001       3M TECHNOLOGIES (S)            PTE LTD.
to 
**28**2      *AC*1001       3* **C********* (*)            *** **D.

The user thought that because MPE/iX is POSIX compliant, that this shoudl 
work.

Clearly not my forte here ;-)......

Could someone steer me in the proper direction ?

Thanks!
Dan Barnes
