pmerge - pascal file merger
pmerge name.p ...
Pmerge assembles the named Pascal files into a single standard Pascal program. The resulting program is listed on the standard output. It
is intended to be used to merge a collection of separately compiled modules so that they can be run through pi , or exported to other
/usr/tmp/MG* default temporary files

Very minimal error checking is done, so incorrect programs will produce unpredictable results. Block comments should be placed after the
keyword to which they refer or they are likely to end up in bizarre places.

ctags - create a tags file
ctags [ -BFatuwvx ] [ -f tagsfile ] name ...
Ctags makes a tags file for ex(1) from the specified C, Pascal, Fortran, YACC, lex, and lisp sources. A tags file gives the locations of
specified objects (in this case functions and typedefs) in a group of files. Each line of the tags file contains the object name, the file
in which it is defined, and an address specification for the object definition. Functions are searched with a pattern, typedefs with a line
number. Specifiers are given in separate fields on the line, separated by blanks or tabs. Using the tags file, ex can quickly find these
If the -x flag is given, ctags produces a list of object names, the line number and file name on which each is defined, as well as the text
of that line and prints this on the standard output. This is a simple index which can be printed out as an off-line readable function
If the -v flag is given, an index of the form expected by vgrind(1) is produced on the standard output. This listing contains the function
name, file name, and page number (assuming 64 line pages). Since the output will be sorted into lexicographic order, it may be desired to
run the output through sort -f. Sample use:
ctags -v files | sort -f > index
vgrind -x index
Normally ctags places the tag descriptions in a file called tags; this may be overridden with the -f option.
Files whose names end in .c or .h are assumed to be C source files and are searched for C routine and macro definitions. Files whose names
end in .y are assumed to be YACC source files. Files whose names end in .l are assumed to be either lisp files if their first non-blank
character is `;', `(', or `[', or lex files otherwise. Other files are first examined to see if they contain any Pascal or Fortran routine
definitions; if not, they are processed again looking for C definitions.
Other options are:
-F use forward searching patterns (/.../) (default).
-B use backward searching patterns (?...?).
-a append to tags file.
-t create tags for typedefs.
-w suppressing warning diagnostics.
-u causing the specified files to be updated in tags, that is, all references to them are deleted, and the new values are appended to the
file. (Beware: this option is implemented in a way which is rather slow; it is usually faster to simply rebuild the tags file.)
The tag main is treated specially in C programs. The tag formed is created by prepending M to the name of the file, with a trailing .c
removed, if any, and leading pathname components also removed. This makes use of ctags practical in directories with more than one pro-
tags output tags file

Ken Arnold; FORTRAN added by Jim Kleckner; Bill Joy added Pascal and -x, replacing cxref; C typedefs added by Ed Pelegri-Llopart.
Recognition of functions, subroutines and procedures for FORTRAN and Pascal is done is a very simpleminded way. No attempt is made to deal
with block structure; if you have two Pascal procedures in different blocks with the same name you lose.
The method of deciding whether to look for C or Pascal and FORTRAN functions is a hack.
Does not know about #ifdefs.
Should know about Pascal types. Relies on the input being well formed to detect typedefs. Use of -tx shows only the last line of type-
