➕ STEP keyword for LINE statement

 BAM now supports the "STEP" keyword in the LINE statement.

Syntax now supported by BAM:

• To draw a line from one coordinate to another:
  LINE (x1,y1) - (x2,y2), Color

• To draw a line from the last pen position to another coordinate:
  LINE - (x2,y2), Color

• To draw a line from one coordinate to a position relative to the first coordinate:
  LINE (x1,y1) - STEP (x2,y2), Color

For each of the syntax forms above, they can also have the optional "box-fill" parameter.

"box-fill" can be "B" for a hollow box, or "BF" for a filled-in box.

• To draw a line from one coordinate to another:
