Here is the code I wrote. I'm unable to push a 'value' on the appropriate array. <code></p> <pre><code> #!/usr/bin/ruby jobs={} #holds everything currentjob="" files=[], pdsmems=[], includs=[], procs=[], programs=[], utilpgms=[] ARGF.each do |line| # chop the line into fields, # where every field is a 'name=value' pair. line.chomp! fields = line.split(' ') print "Currentjob = &gt;#{currentjob}&lt;\n" for field in fields do fieldname, value = field.split('=') # split into name, value #print "&gt;&gt; #{fieldname}=#{value}\n" if fieldname =~ /[jJ]ob/ if currentjob != value print "NEW JOB #{fields[0].split('=')[1]}\n" # this is a new job, so build the hash for old one files=[], pdsmems=[], includs=[], procs=[], programs=[], utilpgms=[] jobelements = {'file' =&gt; files, 'pdsmem' =&gt; pdsmems, 'include' =&gt; includs, 'proc' =&gt; procs, 'program' =&gt; programs, 'utilpgm' =&gt; utilpgms} jobs[value] = jobelements #print "Hash assigned. job = #{jobs} \n" currentjob = value end next end print "fieldname = #{fieldname}\n" # push 'value' on the appro. array in the 'jobelements' hash # which is value of the 'currentjob' key. #jobs[currentjob][fieldname].push(value) # &lt;== HELP! #jobs[currentjob][fieldname] &lt;&lt; value # &lt;== HELP! end end #print the data structure print jobs </code></pre> <p></code></p> <p>I can't seem to get the syntax right to reference the correct array and push an elemnt onto it. Help appreciated. Cheers! P.S.</p> <p>The expected output is like below:</p> <pre><code>["C201A005", {"file"=&gt;["PC201.AD.SRVCPT.INPUT", "ULDH.REHOST3.LOADBTCH", "SYS2.DB2DBP1.SDSNLOAD", "SYS2.DB2DBP1.RUNLIB.LOAD", "SYS2.S99I0062.PROD.SCSQLOAD", "ULDH.REHOST3.REXX", "PROD.NET.MSGS"], "pdsmem"=&gt;["ULDH.REHOST3.PARM/SA005"], "include"=&gt;["PC201", "SORT", "BATC2P"], "proc"=&gt;["RUNTRACN", "DD0005", "ABENDJOB"], "program"=&gt;[], "utilpgm"=&gt;["IEFBR14", "SORT"]}] ["C201A018", {"file"=&gt;[], "pdsmem"=&gt;[], "include"=&gt;["PC201"], "proc"=&gt;["RUNTRACN"], "program"=&gt;[], "utilpgm"=&gt;[]}] </code></pre>
