length to 132 columns for output sent to the printer. (80-column printers must beoperated in compressed mode to make their carriages effectively 132 columns wide.)The video screen is 80 columns wide. For the data file, there is no restriction onwidth. Also for the data file, no attempt is made to line up items in columns.Next in ascan is the scan_head macro, called to do the general initialization. Allscan macros call scan_head .The default definition of scan_head isdef scan_headwhere _head is defined as,’_head’def _head ’_scan_timewaitall; get_angles; calcHKLNPTS = T_AV = MT_AV = 0DATE = date()TIME = TIME_END = time()_cp = A[_pmot]rdef cleanup "_scanabort"# DATA FILE HEADERond; offtprintf("\n#S %d %s\n#D %s\n",++SCAN_N,HEADING,DATE)if (_ctime < 0)printf("#M %g (%s)\n", -_ctime, S_NA[MON])elseprintf("#T %g (%s)\n", _ctime, S_NA[sec])printf("#G")for (_i=0; _i

Next, _headinitializes some variables. NPTS is the loop variable in the scans that will run from 0to _n1 . T_AV and MT_AV maintain the average temperature (from the global variableDEGC )and the average monitor counts or time per point during the scan. DATE andTIME are set to the current date and time. TIME_END is updated at each point withthe current time. The _cp variable is used in powder mode and is set to the centerposition of the powder-average motor.Next in the header macro, the real space motor positions and the reciprocal-spaceposition are made current with getangles and calcHKL . The cleanup macro isdefined to be the standard macro _scanabort . The macro named cleanup is <strong>spec</strong>ialas <strong>spec</strong> automatically invokes that macro when a user types ˆC or on any other error,such as hitting motor limits, trying to go to an unreachable position or encounteringasyntax error in a macro. The definition of _scanabort is,def _scanabort ’_cleanup2_cleanup3comment "Scan aborted after %g points" NPTSsyncundef cleanup’The _cleanup2 macro is defined for delta scans to move motors back to their startingpositions. The _cleanup3 macro is available to users for defining some kind of privateclean up actions.INTERIM WORK-IN-PROGRESS (8/16/01) NOT FOR GENERAL DISTRIBUTION STANDARD MACRO GUIDE 159
