[ExM Users] multiple returns allowed in Swift/T

[Ketan Maheshwari]

Hi Tim,

I made the change as you suggested but now I am getting java NPE:

$ stc mimo.swift > mimo.tcl
STC INTERNAL ERROR
Please report this
java.lang.NullPointerException

    at exm.stc.ui.Main.main(Main.java:93)

The script is as below:

import files;
import io;
import string;
import sys;

app (file _outB1, file _outB2, file _outB3) A (file _inA1, file _inA2, file
_inA3){
    "mimo.sh" @_inA1 @_inA2 @_inA3 @_outB1 @_outB2 @_outB3 @_outB4;
    }

main{

file in_a1=input_file("sample.txt");
file in_a2=input_file("sample.txt");
file in_a3=input_file("sample.txt");
file in_a4=input_file("sample.txt");

foreach i in [0:1]{
   string outb1=sprintf("/tmp/swift.work/outb1-%i.dat", i);
   string outb2=sprintf("/tmp/swift.work/outb2-%i.dat", i);
   string outb3=sprintf("/tmp/swift.work/outb3-%i.dat", i);
   string outb4=sprintf("/tmp/swift.work/outb4-%i.dat", i);

   file o1 <outb1>;
   file o2 <outb2>;
   file o3 <outb3>;
   file o4 <outb4>;

   (o1, o2, o3, o4) = A (in_a1, in_a2, in_a3, in_a4);

}
}

Thanks,
Ketan
