[Coco] OS9 Script Error Handling or File Testing ?

[coco at jechar.ca]

IS THIS CORRECT FOR EXAMPLE ?

if -w /dd/cmds true  then cd /dd/cmds else echo "You do not have 
Permission to Install to this System" endif
if -w /dd/cmds true  then ar2 -x proramarchive.ar else echo exit endif

Would this also be correct

if -w /dd/cmds true then
    cd /dd/cmds
    ar2 -x proramarchive.ar
else
    echo "You do not have Permission to Install to this System"
    exit
endif
