echo . %0 is a demo providing a simple example of the usage of the LSAM
echo . system. The sequence of events will be as follows:
echo . 1) Set environment variables required for demo.
echo . 2) Generate an input control file for DLSCAN using GENPARM.
echo . 3) Show a formatted display of this file using PARMLIST.
echo . 4) Generate a fixed-length file w/'.CLF' extension from an
echo . unformatted '.CAT' file using DLFORMAT.
echo . 5) Build 3 indices and then browse the formatted '.CLF' file
echo . in both directions on any of three 'key' fields using
echo . DLSCAN, which makes use of LSAM calls.

echo . If the required files for this LSAM demo are NOT in the above direc-
echo . tory, hit CTL-C or CTL-BREAK and move them here to simplify things.
echo . When you are ready, restart this batch file. If this is NOT
echo . the case, please proceed. The required files are:
echo . GENPARM.EXE PARMLIST.EXE DLFORMAT.EXE DLSCAN.EXE
echo . LSAM.RTL DL3.TXT DL3.CAT

rem NOTICE - If for some reason you have scattered these files,
rem insert 'd:\path' in environment vars below with demo
rem path information (i.e. where you dumped the demo files).
rem They should look similar to the following:
rem set inctl=d:\path\dl3.bin
rem set lsamrtl=d:\path\lsam.rtl
rem set lsamixalloc=3
:setenv
set inctl=dl3.bin
set lsamrtl=lsam.rtl
set lsamixalloc=3
set
echo .
echo . Note - Environment is now set for DLSCAN demo:
echo . Required LSAM variables LSAMRTL and LSAMIXALLOC are set,
echo . and a user variable 'INCTL' now points to the LSAM
echo . control file for DL3 - DL3.BIN - which contains all
echo . other required attribute information for LSAM to pro-
echo . cess requests against the multi-indexed DL3.CLF.
