Using macro to execute a command in Shell Command

Hi All,

I am trying to execute a command using shell script but I am only able to open files but not execute.

I tried the following but none of them work code:

Shell ("cmd /k 'glpsol.exe -m transp.mod'")
shell ("cmd /c start glpsol.exe -m transp.mod) -- it returns an error stating no file exists

Can some one help me,
