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;
