Duplicate Fields ___________________________________________
If a line of data is identical to a previous bitmap or next-bitmap field, the
duplicate field allows you to repeat the dot sequence without retyping the data.
A duplicate field represents one row of dots on the image.
NOTE: Duplicate fields are useful when you have a graphic with a lot of
repetition.
Syntax D,adjdir,adjamt,count¦
D Identifies a duplicate field.
adjdir Do you want to increment or decrement the row count? (Insert the duplicate
line after or before the current row?)
0 Increments (inserts after)
1 Decrements (inserts before)
For example:
B,50,35,R,”GsSsG”
¦
D,0,20,2¦
inserts row 50 again at row 70 and row 90. Rows 70 and 90 do not
have to be defined later.
adjamt Amount of row adjustment in dot rows. The above example adjusts the
duplicate field to image on row 70 and 90 (adding 20 to the current row count.)
count Number of times to duplicate. (How many times do you want to repeat the
line?)
Example B,117,24,H,”03FFFFFFFFFFFFFFFFFFFC”¦
D,0,1,2¦
