Problem Note 20562: PROC APPEND step may damage BASE data set
If PROC APPEND is used to update the same BASE data set more than once,
the BASE data set may become damaged. The APPEND step will not generate
errors, but any step used to modify the BASE data set later will result
in the following error:
ERROR: Attempt to reference a page past end-of-file on
<lib>.<dsn>.DATA
To circumvent the problem, add the option APPENDVER=V6 to the second
APPEND step, as in the following example:
proc append base=base data=data appendver=v6;
run;
