Another question on "Call" instruction

Just finished reading P Lucas's question.

Can an instruction be placed in front of the "Call" instruction?
(I have just finished work and haven't proved this.)
Existing code:

PB 10
Seg1.

:C DB254
:***
DB254 (Machine timing values)
DW0 KT=002.1
etc
etc

The machine has two recipes, both use the same timing values.
Due to changes there needs to be a third recipe added, in which
these values need to be changed and thus machine speed will quicken.

I was hoping to program DB255 with new timing values for third recipe.
New code
PB 10
Seg 1
If recipe1 or 2 selected Call DB254
If recipe3 selected Call DB255

Is this possible?

Thanks

You can do it this way. ALWAYS open a block first

:C DB254 //Recipe 1 or 2
:A I 0.0 / Load recipe #3 if = 0
:JC DATA //Jump to data area
:C DB255 // recipe #3

DATA :L DW0
:T FW0
:etc
:etc
