EXTRACT V1.6   - Extract records from VMS file
Written by Pat Rankin

VAX binaries produced under VAX/VMS V5.5-2
Alpha binaries produced under OpenVMS Alpha V6.2

EXTRACT is a VMS-specific utility for quickly selecting groups of
records out of files.  It has options for choosing them from the
beginning via /HEAD=n, the middle via /RECORD=(START=m,END=n,COUNT=k),
or the end via /TAIL=n.  Selected records can optionally undergo
various transformations such as alphabetic case conversion, white
space condensation or tab expansion, translation between ASCII and
EBCDIC, or selection of specific sets of columns.  See extract.doc
for more details or extract.hlp for full command syntax.

EXTRACT can be defined as a native DCL command or used as a foreign
command.  The source code is written in Fortran and should compile
as-is for either Alpha or VAX.  File access is accomplished by direct
RMS calls rather than through the Fortran run-time library and is
generally quite fast.
