XMT program
-----------

Purpose:	To convert files from various formats to other formats

Operating System:	RSX-11M Version 3


Calling:	RUN $XMT
		XMT>file1=file2/switches

		file1		output file
		file2		input file

Switches:	/EB	ASCII-to-EBCDIC conversion
		/AS	EBCDIC-to-ASCII conversion
		/UC	lower-to-upper-case conversion (ASCII)
		/UCX	as /UC, but also converts | (ASCII 174) to ! (ASCII 041)
		/BL	replace empty line by a single space (ASCII)
		/-BL	delete trailing blanks
		/FTN	gives the output file the FORTRAN carriage control
			attribute (default is CR/LF attribute)
		/CRLF	search the input for CR/LF separators
			each separator starts a new record in the output file
		/-CRLF	don't search for CR/LF (must be specified for binary
			files) N.B. default is /CRLF !
		/RC:n	split input record in fixed length records of length n
			and generate a fixed-length record file
		/TR	truncate input records to length specified by /RC:n
		/TR:n	truncate input records to length n
		/TR:m:n	delete first m characters and truncate at next n chars
			If also /RC is given n must be equal to or a multiple
			of the RC parameter
			N.B. /RC:n/TR generates fixed-length records of length n
			     /TR:n generates variable-length records of length n
		/DE	delete input file after successful conversion
		/SP	spool output file to lineprinter
		/P:C	clear the parity bit of all input characters
		/P:S	set the parity bit of all input characters
		/P:O	generate odd parity bits
		/P:E	generate even parity bits
			default is no parity handling

Magtape input:	specify MTxx: (or MMxx:) for file2
		The tape must be unmounted, unlabelled with each block =
		1 input record. By using the /RC:n switch this record may be
		split into several smaller records.
		If the tape is preceded by a tape mark (i.e. an empty 'label')
		the switch /TM must be used.

		The following switches may be used for magtape input only:

		/RW	rewind the tape before the operation
			(default is no rewind)
		/DENS:x	spefify the tape density
			x=1600 or 16 for 1600 BPI (MM: only)
			x=800 or 8 for 800 BPI
			x=556 or 5 for 556 BPI (MT: only)
			x=200 or 2 for 200 BPI (7 track MT: only)
			default is 800 BPI or the last one specified
			(the density is not reset between successive commands)
		/TM:m:n	specifies the number of tape marks to be skipped
			m= number of tapemarks to be skipped before the operation
			n= number of tapemarks to be read before the operation stops
			default is m=0, n=1
			/TM means /TM:1:1
			/TM:n means /TM:0:n

Magtape output:	specify MTxx: (or MMxx:) for file1
		The tape will be written as 1 block per record

		The following switches are applicable for magtape output:

		/RW	see above
		/DENS	see above
		/-EOF	don't write a tapemark after the output
			default (/EOF) means 2 tapemarks are written
			with a backspace over the last one

		It is not possible to copy from magtape to magtape.


		COMBINATIONS OF SWITCHES ARE POSSIBLE, BUT BEWARE OF PECULIAR
		SIDE EFFECTS!!!
