Subject:      missing values

I'm working with a large dataset (~500,000 records) and need to recode
missing values.  Currently values of -1, -7, -8, and -9 represent missing
values (note these are used in both character and numeric fields).

I'm an inexperienced user and all I could think of was to treat the
dataset as an array and test each value to see if it is a missing value (-
1, -7, -8, -9) and if so set it to . or " ".  However this would require
me to separately test numeric and character variables and seems
computationally intensive.

I'm guessing there's a much better way to approach this problem.  I'm very
grateful for any suggestions.
