Problem Note 38643: "Write Access Violation" error issued with PROC FREQ two-way table with the MISSING= option
 |  |  |  |
The following error might be issued when generating a PROC FREQ two-way table where one of the variables contains all missing values and OPTIONS MISSING=' ' has been specified:
ERROR: Write Access Violation In Task [ FREQ ]
In addition to the error, only some header information will display in the results.
To circumvent the problem, create a user-defined format to display blanks for missing values instead of specifying the MISSING=' ' option on an OPTIONS statement. The code below illustrates the circumvention.
data test; /* creating sample data set */
a=1; b=.; output;
a=2; b=.; output;
a=2; b=.; output;
a=3; b=.; output;
a=3; b=.; output;
a=3; b=.; output;
run;
proc format;
value myfmt
.=' '
other=[8.];
run;
options missing=' ';
proc freq data=test;
table a * b / missing;
format b myfmt.;
/* Removal of or commenting the FORMAT statement will result in the error */
run;
