1 reset
 reset all spectra which are defined by the program
 most recently compiled.
 A single spectrum can also be reset.
 format:
	reset		! reset all
	reset spectrum,<spectrumname>
1 write
 Write all or a group of spectra to a spectrum file.
 format:
	write to,<prefix> [subcommands]
2 to
 Define the spectrum file by the means of a prefix. The
 spectrum file must be connected to the program by the
 connect command. You can also write to an output tape
 by the command : write to,tape ...
2 all
 Write all spectra to the spectrum file. (default)
 format:
	write all [...]
2 spectrum
 Write one or more spectra given by their names to the spectrum
 file (or magtape). The names are those as given by the eval code.
 format:
	write spec,<s1>,<s2>,...,<sn>
 e.g.
	write spec,spde,spe
1 list
 List the current content of variables , gates and spectrum names and
 sizes.
1 change
 Change the content of a variable or gate.
1 exit
 leave the vaxeva program. 
 NB! All data are lost including the spectra.
1 read
 read a tape file or part of tape file for sorting according to
 the compiled eval program. You must specify the filenumber
 ( counted as 0,1,2...) . Optionally you can give the first block
 and the number of blocks to be read.
2 file
 Specify the file ( and block)
 format:
	read file,<filenumber>[,<blockno>] ...
2 blocks
 Input the number of blocks to be read for this sorting.
 format:
	read blocks,<number of blocks>  file,...
1 set
 Set the content of controlling variables, titles etc.
 format:
	set <subcommand>,<parameters>
2 conversion
 Set the conversion mode. possible conversions are
 0 : no conversion
 1 : BNL sigma-7  event tape format
 2 : RC4000 conversion 24 bit words into 32 bit words
 3 : Byte swapping of input tape (LASL p-9)
2 title
  Set the current character string to be output as the title
  of spectra which are written to disc or tape.
   The title is normaly taken from a tape header when such exists.

  The program asks you to type the new title
2 run
  Set the current run number to be used in the headers of subsequent
  spectrum dumps.
 format:
	set run,<runnumber>
2 user
  Set the user id to be used in the headers of subsequent spectrum
  dumps.
 format:
	set user,<userid>
				! userid is a characterstring.
