 In REXX, there are no minimums for variables holding character literals, so you just simply assign (set) character strings to REXX variables.
-<br>Note that REXX stores all the values of variables as characters, and that includes numbers and booleans.
+<br>Note that REXX stores all the values of variables as characters, and that includes numbers (all kinds), booleans (logical), and labels (including subroutine/function names).
-<br>However, to insure that REXX can store numbers with a minimum size, the '''NUMERIC DIGITS nnn''' instruction can be used.
