Improperly structured or improperly placed macro statements will generate an alarm. Be careful when editing expressions; brackets must be balanced.

The DPRNT[ ] function can be edited much like a comment. It can be deleted, moved as a whole item, or individual items within the bracket can be edited. Variable references and format expressions must be altered as a whole entity. If you wanted to change [24] to [44], place the cursor so that [24] is highlighted, enter [44] and press ENTER. Remember, you can use the HANDLE JOG control to maneuver through long DPRNT[ ] expressions.

Addresses with expressions can be somewhat confusing. In this case, the alphabetic address stands alone. For instance, this block contains an address expression in X:

G01 G90 X [COS [90]] Y3.0 (CORRECT) ;

Here, the X and brackets stand-alone and are individually editable items. It is possible, through editing, to delete the entire expression and replace it with a floating-point constant.

G01 G90 X 0 Y3.0 (WRONG) ;

The above block will result in an alarm at runtime. The correct form looks as follows:

G01 G90 X0 Y3.0 (CORRECT) ;
note: There is no space between the X and the Zero (0). REMEMBER when you see an alpha character standing alone it is an address expression.
