In Operator

Description
The in operator is used in logical expressions to test whether an item or variable is within a set of values or ranges. The item or variable can be a number or a string. A range of values is separated by a colon, for example 1:5. Elements of a list of values or ranges are separated by commas, for example 1,3:5,7. You can also use special to mean all special values (as in the special function). The in operator can also be used to test whether a value is in several CSPro objects:
  • A list can be used to determine if the value is located in the list's values (as in the list.seek function).
  • A value set can also be used to test whether a value is in the value set's codes (as in the invalueset function).
Example 1
if RELATIONSHIP in 1:5 then
// is the same as...
if RELATIONSHIP >= 1 and RELATIONSHIP <= 5 then
Example 2
if WORK in 1, 3, 5 then
// is the same as...
if WORK = 1 or WORK = 3 or WORK = 5 then
Example 3
if X in 1:4, missing, refused then
// is the same as...
if ( X >= 1 and X <= 4 ) or X = missing or X = refused then
Example 4
if NAME in "A":"MZZ" then
// is the same as...
if NAME >= "A" and NAME <= "MZZ" then
Example 5
if AGE in AGE_TEENAGE_VS, special then
// is the same as...
if invalueset(AGE, AGE_TEENAGE_VS) or special(AGE) then
