Subject:      Unix scripting question: keeping -sysparm quoted

Hi,

This question is specific to Unix.  If you're not working with SAS on Unix
just hit delete or ignore.

Summary:  I have a series of Unix scripts nested about 4 deep.  I need to
set the -sysparm parameter from the top level script to control the
processing of the SAS program.  The quoting of -sysparm is not being
maintained properly, and SAS issues an error.

Details:  I have the following scripts:

RunAll_DDB.sh:  This is the top level script ("one liner"):

./RunAll.sh RunAllUnix_DDB.sas "$@"

RunAll.sh:  This is used for a variety of SAS prgrams:

pgm=$1
shift

if [[ $# -gt 0 ]]; then sysparm="-sysparm \"$@\""; else sysparm=""; fi

print \
sas -sysin $pgm $sysparm -rsasuser -noterminal
sas -sysin $pgm $sysparm -rsasuser -noterminal

The "sas" script:  This is a local script:

#!/usr/bin/ksh
[[ $TERM = "vt220" ]] && TERM="vt220-nam"
if [[ $SAS_ROOT != "/sas913" ]]
then
    echo "SAS directory $SAS_ROOT is invalid for this server"
    exit 1
fi
SAS_CONFIG="$SAS_ROOT/sasv9.cfg"
if [ ! "$DISPLAY" ]
then
  SAS_OPTIONS=$SAS_OPTIONS" -NODMS"
fi
echo $@
SAS_WORK="$(saswork)"

#export SAS_ROOT SAS_WORK

echo "$SAS_ROOT/sas $SAS_OPTIONS -work $SAS_WORK $@"
$SAS_ROOT/sas $SAS_OPTIONS -work $SAS_WORK $@

(Note:  I've also overridden that "sas" script with my own, trying:

$SAS_ROOT/sas $SAS_OPTIONS -work $SAS_WORK "$@"
$SAS_ROOT/sas $SAS_OPTIONS -work $SAS_WORK $*
$SAS_ROOT/sas $SAS_OPTIONS -work $SAS_WORK "$*"


$SAS_ROOT/sas is SAS's script.  At my site it is installed in /sas913/sas.
I won't print the entire file, but it contains the line:

#   This is a generated script.  Do not edit this file.

then later, the business end of the script...

exec $SAS_INSTALL_ROOT/hotfix/sasexe/sas "$@"


Sorry for all the details - hopefully it makes sense to someone out there!!!

The various "echo" commands display this in my shell:

RunAllUnix_DDB.sh d4* (I want to run all the d4* programs)
sas -sysin RunAllUnix_DDB.sas -sysparm "d4xxxx.sas d4yyyy.sas d4zzzz.sas"
-rsasuser -noterminal
\-sysin RunAllUnix_DDB.sas -sysparm "d4xxxx.sas d4yyyy.sas d4zzzz.sas"
-rsasuser -noterminal
/sas913/sas -autoexec /proj/some/pharma/company/autoexec.sas -work
/saswork/tmp7 -sysin RunAllUnix_DDB.sas -sysparm "d4xxxx.sas d4yyyy.sas
d4zzzz.sas" -rsasuser -noterminal
ERROR: Invalid file, /proj/some/pharma/company/programs/d4zzzz.sas".sas.

Everything *looks* OK in the shell output - sysparm stays quoted throughout
the script invocations (or at least the "echo" statements).  But, the final
error message is indicative of -sysparm not being "really" quoted.

If I cut-and-paste the final SAS command line and submit it directly in the
shell, the command works fine.

Does anyone know how to maintain the quoting of the -sysparm argument
throughout a series of nested scripts?

Thanks,
Scott
