Effect of scaling on GAMS output

GAMS automatically descales all solution information so scaling does not affect the solution output.   However, the LIMROW/LIMCOL output from GAMS displays the elements after scaling and an option in GAMSCHK controls whether the data displayed are before or after scaling.  The GAMSCHK DISPLAYCR, MATCHIT, BLOCKPIC and BLOCKLIST ordinarily print out information on an after scaling basis but POSTOPT is on a before scaling basis.
