The data files created by the macros have a simple format. The files are ASCII. Control lines in the file begin with a # followed by a upper-case letter. Other lines are blank or contain scan data.

The control conventions are:

Code	Parameters	Description
#C	comment	Comments inserted by many of the standard macros.
#D	date	A string representing the current date, in the format Wed May 4 23:59:49 1988.
#E	seconds	The UNIX epoch at the time the file was created.
#F	filename	The name by which the file was created.
#G1	parameters	Array G[] (geometry mode, sector, etc.)
#G2	parameters	Array U[] (lattice constants, orientation reflections)
#G3	parameters	Array UB[] (orientation matrix)
#G4	parameters	Array Q[] (LAMBDA, frozen angles, cut points, etc.)
#I	factor	A normalizing factor to apply to the data.
#jN	mnemonics	Counter mnemonics (N = 0,1,2,... eight per row)
#JN	names	Counter names (N = 0,1,2,... eight per row, each separated by two spaces)
#L	labels	Labels for the data columns (each separated by two spaces)
#M	counts	If counting to monitor counts, the number of counts.
#N	num [num2]	The number of columns of data that follow (num2 sets per row)
#oN	mnemonics	Motor mnemonics (N = 0,1,2,... eight per row)
#ON	names	Motor names (N = 0,1,2,... eight per row, each separated by two spaces)
#PN	positions	Postions of motors corresponding to #O/#o above.
#Q	H K L	A reciprocal space position.
#R	results	User-defined results from a scan.
#S	number	A new scan having scan number number follows, normally preceded by a blank line.
#T	seconds	If counting to time, the time used.
#U		Reserved for user.
#X	setpoint	The temperature setpoint.
#@MCA	fmt	This scan contains MCA data (array_dump() format, as in "16C")
@A	data	MCA data formatted as above
#@CALIB	a b c	T{
Coefficients for x[i] = a + b i + c
i2for MCA data.
T}
#@CHANN	n f l r	T{
MCA channel information (number_saved, first_saved, last_saved, reduction coef)
T}
#@CTIME	p l r	T{
MCA count times (preset_time, elapsed_live_time, elapsed_real_time)
T}
#@ROI	n f l	T{
MCA ROI channel information (ROI_name, first_chan, last_chan)
T}
