title: How to compile with GnuCOBOL
body: <p>I am trying to add a task to compile a program but am having difficulty with setting environment variables. I have this:</p>
  
  <pre><code>{
    // See https://go.microsoft.com/fwlink LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
     "label": "GnuCOBOL - Compile (single file)",
     "type": "shell",
     "options": {
      "env": {
          "PATH=c:\\gnucobol3\\bin"
          "COB_CONFIG_DIR=c:\\gnucobol3\\config"
          "COB_COPY_DIR=c:\\gnucobol3\\copy"
          "COB_INCLUDE_PATH=c:\\gnucobol3\\include"
          "COB_LIB_PATH=c:\\gnucobol3\\lib"
         },
      "command": "cobc",
      "args": [
        "-x",
        "-std=mf",
        "-tPROG.LST",
        "BBCB.CBL"
        ]
      },
  } 
  </code></pre>
  
  <p>The env entries all have squiggly lines underneath and show errors "Colon expected".</p>
  
  <p>I'd appreciate some help. Thanks.</p>
