Characters

Characters (usually shown as CHAR) are typically used within a CLEM expression to perform tests on strings.

For example, you can use the function isuppercode to determine whether the first character of a string is upper case. The following CLEM expression uses a character to indicate that the test should be performed on the first character of the string:

isuppercode(subscrs(1, "MyString"))

To express the code (in contrast to the location) of a particular character in a CLEM expression, use single backquotes of the form `<character>`. For example, `A`, `Z`.

Note: There is no CHAR storage type for a field, so if a field is derived or filled with an expression that results in a CHAR, then that result will be converted to a string.
