A magic also available in Turbo BASIC.
Ironically Borland gave up competing against Microsoft on BASIC tooling, while Microsoft gave up competing against Borland on Pascal tooling (Quick Pascal).
Both products where short lived, Microsoft killed Quick Pascal quite quickly, while Borland sold Turbo BASIC, which became Power BASIC.
PowerBASIC is dead; the website no longer works. The old PowerBASIC for DOS abandonware can be found here: https://winworldpc.com/product/powerbasic/3x
It is a DOS 16-bit program.
