Questions:
How can I define a symbol for a form feed character, and
for other escape characters as well? I'm working with
large files and only want to write out certain lines
that begin with a form feed character. It looks like
this:
$ read/end_of_file=endit infile record
$ outrecord = F$extract(1,1,record)
$ if (outrecord EQ. xxx)
What do I replace the xxx with?

See an ASCII table for the specific character codes.
In the case of formfeed, the DCL bitfield would be:
$ ff[0,8] = 12.

See the OpenVMS Frequently Asked Question (FAQ) for an
example of the above syntax, see "DECW9. How do I set
the title on a DECterm window?". The OpenVMS FAQ is at

To see if the first character is a FF:
$ read/end_of_file=endit infile record
$ if f$cvsi(0,8,record) .eq. 12 then ... ! only do if FF
