ValueSet.remove Function

Format

i = valueset_name.remove(code);

Description

The ValueSet.remove function removes all values from a ValueSet object that have a code matching the specified numeric or string expression code. The type of the code must match the type of the value set.

When using a numeric value set with ranges (i.e., both from and to codes are defined), or defined special values, the function will remove a value only if it is the from value or if it is the special value.

Return Value

The function returns the number of values with the matching code that were removed from the value set. If the value set is read-only, the function returns default.

Example

PROC SECOND_FAVORITE_DRINK

preproc

ValueSet drink_valueset = FAVORITE_DRINK_VS;

drink_valueset.remove(FAVORITE_DRINK);

setvalueset(SECOND_FAVORITE_DRINK, drink_valueset);
