Batch Reading BMP Files

Does anyone know it is possible to read multiple files into matchcad using 1 command. My BMP's are called Image0.bmp, Image1.bmp, ... etc. I need to convert them to matrices containing the grey values. Out of these matrices I need to extract grey values and then I wish to write these values into a file. Because I do not whish to load over a 100 BMP's into Matchcad manually, I was hoping anyone could help me.

PS: when using for instance "for i from 0..100 READBMP("Imagei.bmp") won't work ofcourse.

Many thanks in advance

Why "of course?"

Did you read the definitions of the string functions?

What version of Mcad are you using?

Current versions allow the argument of read/write commands to be a variable as below:
images:= |a<-"c:/folder/image"
         |for i from 0...100
         |  file<-concat(a,num2str(i),".bmp")
         |  output(sub i) <- READBMP(file)
         |output

However, I believe that older versions did not allow this.  I'm not sure when that changed, maybe with v11?

Thanks guys,

I have MatchCad version 11.0a. My first screening of the tutorials was not succesful. That's why I assumed it wasn't possible. I'll start looking it up right now. Hopefully my Mathcad version allows this.

Thank you for a quick reply!
