How can I change block properties from Xmath?

[JewgenijTarschis]

I want to modify some block properties from Xmath, for example to change name of a constant block. I tried something like

Constant1.name="new name";

Can anyone help me?

Thanks,

Jewgenij

You can use the SBA (SystemBuild Access, see Chapter 7 of the SystemBuild User guide ) routine modifyblock command to change any SystemBuild

block property. All created blocks have a block id which must be specified as part of the modifyblock command.

For example:

      modifyblock 2,{name="myblock",color=2,size=[100,100]}

or to create a gain block

      createblock "gain",{gain=2.5,name="accelConstant"}

to retrieve the block id of a created block, pass in a variable set to zero, createblock will set the variable to the created block id

      myid = 0

      createblock "deadband",{id=myid}

      modifyblock myid,{color=1,inputs=2}

You can also get properties of a block using the queryblock command.

      [t=threshold,c=color,l=location,t=blocktype] = queryblock(myid)

See Chapter 7 of the SystemBuild Users Guide for more commands and details
