%UCS2 converts the value of the expression from character, graphic, or UCS-2 and returns a UCS-2 value. The result is varying length if the parameter is varying length, or if the parameter is single-byte character.
The second parameter, ccsid, is optional and indicates the CCSID of the resulting expression. The CCSID defaults to 13488.
If the parameter is a constant, the conversion will be done at compile time.
If the conversion results in substitution characters, a warning message is issued at compile time. At run time, status 00050 is set and no error message is issued.

C EVAL ufield = %UCS2(char) + %UCS2(graph)
* ufield now has 7 UCS-2 characters representing
* 'a.b.c.d.e.AABB' where 'x.' represents the UCS-2 form of 'x'
C EVAL isLess = ufield < %UCS2(ufield2:13488)
* The result of the %UCS2 built-in function is the value of
* ufield2, converted from CCSID 61952 to CCSID 13488
* for the comparison.
C EVAL ufield = ufield2
* The value of ufield2 is converted from CCSID 61952 to
* CCSID 13488 and stored in ufield.
* This conversion is handled implicitly by the compiler.
C CALLP proc(ufield2)
* The value of ufield2 is converted to CCSID 13488
* implicitly, as part of passing the parameter by constant reference.
