Programming 1980 style!! This project emulates an old fashioned line-numbered BASIC language machine. On a monochrome monitor, of course, and only upper case letters. Green, or amber if you want to get fancy with third party equipment. I have started a new project to convert this to Typescript (see `typescript` branch).
Currently, we can print a numeric value. For example:
120 PRINT X
will print the value of the numeric variable X. However, it can only print a numeric value on a separate line. If we implement a function in Grandpa BASIC to convert numeric values to strings, then users can use string concatenation to print numeric values combined with strings on one line.
For example, instead of
330 PRINT "THE AREA IS"340 PRINT A350 PRINT "SQUARE MILES"
THE AREA IS482.68SQUARE MILES
we could write something like
330 A2="THE AREA IS "+STR$(A)+" SQUARE MILES"340 PRINT A2
