Re: [foxboro] Questions concerning IND-Block / substitution of C:B.P

I don't understand exactly what it is that you are asking in your second
question, but I'll try to answer. =20

You stated that you wanted to get the compound and block name from the
sequence block itself.  (Perhaps you have several sequence blocks with ve=
ry
similar code.)  You may add strings together, but I do not know if you ca=
n
truncate or parse strings (because I've never tried).  But, there is anot=
her
way.... (Isn't there always?)

Getting those values from the sequence block itself implies that they do =
not
change (within an individual block).  You may establish those values in a
constant at the beginning of the program and then combine them as needed
within the code.  The code may still copied from block to block, as neede=
d.
You'll just have to change the value of the constant for each block.
Further, if you are doing this because you have many blocks using the sam=
e
code, you'll probably have "include" files as well.  In that case, save
yourself some time.  Instead of setting the constant in the body of the c=
ode
(under CONSTANTS), put it in the "include" file and be done with it.


For example:

INDEPENDENT_SEQUENCE

CONSTANTS
   CmpBlk =3D "0309:M002.";

USER_LABELS
   Param  : SN0001; { name of parameter )

STATEMENTS
  =20
   /* Here we combine the compound:block with the parameter */
   CBP =3D CmpBlk,Param;

   /* If you like, you can use literal strings, too */
   CBP =3D CmpBlk,"AUTDSR";

ENDSEQUENCE

I may have misunderstood your question, but this is a way to get the
compound and block names from the sequence block itself.  This way, you w=
ill
require only the parameter name from outside the sequence block.

Hi list,


=3D=3D=3D=3D=3D=3D

2nd IND-Block question:

Is ist possible to truncate the name of the IND-Block given by the=20
variable "BLOCK_NAME" that I get "M002" out of "M002_SEQ"
I'd like to automate the adressing with the C:B values given by the=20
Indipendet Block itself



Any assistance will be appreceated.

Best regards
