请高后赐教!

xsc

set x_pnl_size = $gPROF_LIMITSxmax
   set y_pnl_size = $gPROF_LIMITSymax
   set hx_pnl_size = `echo "$x_pnl_size * 0.5" | bc`
   set hy_pnl_size = `echo "$y_pnl_size * 0.5" | bc`
   set x_pnl_min = $gPROF_LIMITSxmin
   set y_pnl_min = $gPROF_LIMITSymin
   DO_INFO -t step -e $JOB/$panel_name -d SR_LIMITS
   set x_sr_size = $gSR_LIMITSxmax
   set y_sr_size = $gSR_LIMITSymax
   set x_sr_min = $gSR_LIMITSxmin
   set y_sr_min = $gSR_LIMITSymin

这几句是什么意思啊?它设定的点在哪里啊?

还有,我想设定在排版时的板角四个点的坐标,该如何设呢?
