+; NAME:
+;    STR_SEP
+;
+; PURPOSE:
+;    This routine cuts a string into pieces which are separated by the
+;    separator string.
+; CATEGORY:
+;    String processing.
+; CALLING SEQUENCE:
+;    arr = STR_SEP(str, separator)
+;
+; INPUTS:
+;    str - The string to be separated.
+;    separator - The separator.
+;
+; KEYWORDS:
+;    ESC = escape character.  Only valid if separator is a single character.
+;		Characters following the escape character are treated
+;		literally and not interpreted as separators.
+;		For example, if the separator is a comma,
+;		and the escape character is a backslash, the character
+;		sequence 'a\,b' is a single field containing the characters
+;		'a,b'.
+;    REMOVE_ALL = if set, remove all blanks from fields.
+;    TRIM = if set, remove only leading and trailing blanks from fields.
+;
+; OUTPUT:
+;    An array of strings as function value.
+;
+; COMMON BLOCKS:
+;    None
+;
+; SIDE EFFECTS:
+;    No known side effects.
+;
+; RESTRICTIONS:
+;    None.
+;
+; EXAMPLE:
+;    array = STR_SEP ("ulib.usca.test", ".")
+;
+; MODIFICATION HISTORY:
+;	July 1992, AH,	CreaSo		Created.
+;	December, 1994, DMS, RSI	Added TRIM and REMOVE_ALL.
