Thanks! This is interesting. I'll see if I can find v9 to test it.

Ya,

If you are running V9, you might want to consider something using CALL MISSING.

Only minimally tested:

data anno; function='label'; color='red'; x=1; y=2; xsys='3'; cy='3'; link op; function='move'; x=1; y=4; link op; function='draw'; x=3; y=5; line=4; link op; return;

op: output; call missing(of _all_); return; run;

proc print; run;

Prost, Puddin'
