modifying a string table entry via automation

Hello,

I want to modify a string table entry value, already present, in my .ism file, via Installshield automation.
But, I can't figure out how to do this.

The entry that I want to modify is in the ISString table.
And I know the ID of the string entry itself.
And I know what I want to change the value to.

I just can’t figure out what the code should look like.

I am already using automation to open the .ism file and change a number of entries for various things, before saving it and then building the .MSI file.

I’d would be grateful  for an example, from someone who has done such a thing.

Thanks in advance for considering my request for help.
