+'In Liberty BASIC variables are either string or numeric.
+'A variable name can start with any letter and it can contain both letters and numerals, as well as dots (for example: user.firstname).
+'There is no practical limit to the length of a variable name... up to ~2M characters.
+'The variable names are case sensitive.
+
+'assignments:   -numeric variables. LB assumes integers unless assigned or calculated otherwise.
+'Because of its Smalltalk heritage, LB integers are of arbitrarily long precision.
+'They lose this if a calculation yields a non-integer, switching to floating point.
+    i = 1
+    r = 3.14
+
+'assignments    -string variables. Any string-length, from zero to ~2M.
+    t$    ="21:12:45"
+    flag$ ="TRUE"
+
+'assignments    -1D or 2D arrays
+'A default array size of 10 is available. Larger arrays need pre-'DIM'ming.
+    height( 3)          =1.87
+    dim height( 50)
+    height( 23)         =123.5
+    potential( 3, 5)    =4.5
+    name$( 4)           ="John"
+
+'There are no Boolean /bit variables as such.
+
+'Arrays in a main program are global.
+'However variables used in the main program code are not visible inside functions and subroutines.
+'They can be declared 'global' if such visibility is desired.
+'Functions can receive variables by name or by reference.
