Get rid of need for GNU diff in `make check'.
Get rid of need for file name canonicalization.
-Format specifier code needs to be rewritten for lowered crappiness.
+Use getsubopt()?
+
+Format specifier and missing values code needs to be rewritten for lowered
+crappiness.
CROSSTABS needs to be re-examined.
Add compression to casefiles.
+There needs to be another layer onto the lexer, which should probably be
+entirely rewritten anyway. The lexer needs to read entire *commands* at a
+time, not just a *line* at a time. It also needs to support arbitrary putback,
+probably by just backing up the "current position" in the command buffer.
+
Scratch variables should not be available for use following TEMPORARY.
+Details of N OF CASES, SAMPLE, FILTER, PROCESS IF, TEMPORARY, etc., need to be
+checked against the documentation. See notes on these at end of file for a
+start.

Check our results against the NIST StRD benchmark results at
strd.itl.nist.gov/div898/strd
PostScript driver should emit thin lines, then thick lines, to optimize time
and space.
+New functions? var_name_or_label(), tab_value_or_label()
+
Should be able to bottom-justify cells. It'll be expensive, though, by
requiring an extra metrics call.
Support multi-line titles on tables. (For the first page only, presumably.)
+Rewrite the convert_F() function in data-out.c to be nicer code.
+
In addition to searching the source directory, we should search the current
directory (for data files). (Yuck!)
Fix som_columns().
+Has glob.c been pared down enough?
+
Improve interactivity of output by allowing a `commit' function for a page.
This will also allow for infinite-length pages.
The manual: add text, add index entries, add examples.
+The inline file should be improved: There should be *real* detection of whether
+it is used (in dfm.c:cmd_begin_data), not after-the-fact detection.
+
Figure out a stylesheet for messages displayed by PSPP: i.e., what quotation
marks around filenames, etc.
+New SET subcommand: OUTPUT. i.e., SET OUTPUT="filename" to send output to that
+file; SET OUTPUT="filename"(APPEND) to append to that file; SET OUTPUT=DEFAULT
+to reset everything. There might be a better approach, though--think about it.

+In addition to an "infinite journal", we should keep a number of
+individual-session journals, pspp.jnl-1 through pspp.jnl-X, renaming and
+deleting as needed. All of the journals should have date/time comments.

+Qualifiers for variables giving type--categorical, ordinal, ...

+Consider consequences of xmalloc(), fail(), hcf() in interactive
+use:
+a. Can we safely just use setjmp()/longjmp()?
+b. Will that leak memory?
+i. I don't think so: all procedure-created memory is either
+garbage-collected or globally-accessible.
+ii. But you never know... esp. w/o Checker.
+c. Is this too early to worry? too late?
+
+Need to implement a shared buffer for funny functions that require relatively
+large permanent transient buffers (1024 bytes or so), that is, buffers that are
+permanent in the sense that they probably shouldn't be deallocated but are only
+used from time to time, buffers that can't be allocated on the stack because
+they are of variable and unpredictable but usually relatively small (usually
+line buffers). There are too many of these lurking around; can save a sizeable
+amount of space at very little overhead and with very little effort by merging
+them.
+
+Clever multiplatform GUI idea (due partly to John Williams): write a GUI in
+Java where each statistical procedure dialog box could be downloaded from the
+server independently. The statistical procedures would run on (the/a) server
+and results would be reported through HTML tables viewed with the user's choice
+of web browsers. Help could be implemented through the browser as well.
