| Format: | $S(test:value,test:value,...) |
| Parameters: |
expression is an expression that can be evaluated as True or False (not zero or zero). value is any expression that can yield a value. |
| Use: | Each value is associated with the test from which it is separated by a colon. The function returns the evaluation of the value associated with the first test that evaluates as true (i.e., not equal to zero). Any number of test:value pairs can be used; however, one of the tests must evaluate as true. To assure that one test will always evaluate as true, the last test is usually the literal 1. |
| Examples: |
$S("Bill Nichols, Ph.D."["M.D.":"He is a medical doctor.",1:"He is not a medical doctor.")=> He is not a medical doctor. $S(OCCURRENCES>3:"Chronic Condition",OCCUR-RENCES>0: "Non Chronic Condition",1:"No Occurrences Recorded")=> Chronic Condition [Here the contents of the OCCURRENCES field is being tested. If the first test (>3) is true (as in this example), the result of the second test (>0) is not relevant.] |
