I'm working with 100's of PS Account 'MONTHLY USAGE'
Reports. I have been able to parse the reports, do a
table lookup to match a Login ID with an Application
Name. My output CSV at this point is as follows: 

Login ID,Application,CPU Minutes,Percent of Total
s2pe,CTI Production ,8455,21.7%
sybprd01,OMS,5326,13.7%
pctip01,CTI,5098,13.1%
lxsadr54,CTI,1742,4.5%
pipmp01,SSG-IPM,1742,4.5%
maestro,SSG-RAC-Maestro ,1020,2.6%
f2pa,"DB2DARI  ""stored procedures"" prod",836,2.1%
pomgp01,SSG-PMD-Omegamon,56,0.1%
pptip01,PTI - Private Client Services,16,0.0%
pbmwp01,BMW,3,0.0%
s2pv,Merva,1,0.0%

I am trying to accumulate the CPU Minutes and/or the
Percent of Totals by Application. A real example will
have multiple Login ID's per Application (the 2nd
field). I know how to do this using SAS, but an unsure
of how I might accomplish this in perl.
