|dynarray||An expression that resolves to a dynamic array.|
The LOWER function returns a dynamic array with its delimiters converted to the next lower-level delimiters. For example, @VM value mark delimiters become @SM subvalue mark delimiters. When a delimiter cannot be lowered any further, it is returned unchanged. A dynarray value that does not contain dynamic array delimiters is returned unchanged.
The available levels, in descending order, are: @IM (CHAR(255)); @FM (CHAR(254)); @VM (CHAR(253)); @SM (CHAR(252)); @TM (CHAR(251)); and CHAR(250).
The RAISE function performs the opposite operation, raising the level of dynamic array delimiters to the next higher level.
The following example uses the LOWER function to convert dynamic array delimiters to the next lower level. It then uses the RAISE function to reverse this operation:
numvm=123:@VM:456:@VM:789:@VM:"10":@VM:"11" PRINT numvm; ! Returns 123ý456ý10ý11 numlower = LOWER(numvm) PRINT numlower; ! Returns 123ü456ü10ü11 numraise = RAISE(numlower) PRINT numraise; ! Returns 123ý456ý10ý11
