What's the best way to parse a long SQL statement into a string variable?

For example:

cquery = "select mastddup.location, mastddup.census, ;
mastddup.name,mastddup.addr1, mastddup.city, mastddup.state, mastddup.zip,;
mastddup.zip4,bs_arch.location, bs_arch.mail_date,bs_arch.mail_code from mastddup,;
bs_arch where mastddup.location=bs_arch.location and bs_arch.mail_date >= '19981201' "

The problem I've got with this particular string is the last "and" clause. I keep getting syntax errors.
