-
- I have tried quite a few public domain cross reference generators
- for Turbo Pascal. Most of them had some nice features but a good
- many of them were also unreliable or out-dated. The most common
- problem I had was a limitation on the size and complexity of the
- source code. After a certain point they could no longer generate
- a cross reference.
-
- TPX makes extensive use of dynamic memory and data structures; it
- is capable of handling very large programs. It produces a
- compressed listing consisting of the line number, level number,
- and source code reference line. This program was written for use
- with an Okidata µ92 Plug 'n Play - it may not be compatible with
- some other printers.
-
-
- -METHOD-
-
- Each line of the source file is read and then parsed. When a
- reference word is found, (a word not reserved by Turbo Pascal),
- it is inserted in a binary tree. Each node of the tree contains a
- reference word and a pointer to a linked list. The linked list
- contains a node for each line on which the referenced word is
- found. When the file has been completely read and parsed an in-order
- transversal of the binary tree is performed and the cross
- reference is listed.
-
-
- -USAGE-
-
- The command structure is as follows:
-
- TPX file-name [L|X]
-
- or
-
- TPX ?
-
- Where:
-
- file-name = source file
-
- X = produce only the cross reference
-
- L = produce only a source listing
-
- ? = display an information screen
-
- The program also checks for the following command strings (these
- must begin in column 1):
-
- {%P} = force a new page
-
- {%H} = stop processing until the
- {%H} is found
-
- {%C "string"} = set comment string. This
- string is printed in the
- header following the
- file name. The string is
- specified between the
- quotation marks.

- If you find this program useful please drop me a post card,
- (something with a picture on it people - regular postal cards are
- so boring!), it would be appreciated and would indicate to me whether
- further development of this program is warranted.
