(SLEN(text))
Returns the length of a text string.
SLEN can be used to ensure that a string does not exceed the space allowed for it on a form, variable form, or report. When strings are concatenated or passed as parameters to a procedure file, the length of a string might be unknown.
In the following example, the value of vslen is 5, the number of characters in the text string.
SET VAR vslen = (SLEN('ABCDE'))
