51642 - Using a negative array subscript might generate the error "Array subscript out of range"

Problem Note 51642: Using a negative array subscript might generate the error "Array subscript out of range"

Error messages similar to the following can be generated when you use a variable that has a negative value as an array subscript:

ERROR: Array subscript out of range at line 4 column 5.

NOTE: The SAS System stopped processing this step because of errors.

The error can occur even if the subscript value is valid.

The example code below results in an incorrect error message:

data _null_;

   array pm[-7:0] (1, 1, 1, 1, 1, 1, 1, 1);

   i=-1;

   x = pm[i];

run;
