 Hi Hugh --

 First, let me say the novice package looks tremendously interesting. However, I feel I'm nod advanced enough to work through your documentation. May I suggest you write a very simple tutorial, with examples?

 On what regards your suggestions, I don't think I'm making my self clear. Let me try again:

 I already have what I call "a database with a DSL for free". They are the little recipes we write in shorthand.

 What I would like to do next is to be able to create functions that will write back the Forth code to file, in that format I specified. I should add: I would like to have words for input that:
 -  take in a line in "prescription shorthand" (they are triplets but not necessarily, e.g, HCTZ25 30P 1PM")
 -  I don't want to declare, say, 20 variables beforehand in the code, expecting the case a patient will have 20 drugs to renew (might happen...for a few patients...). If I use BUFFER:, for instance, I have to declare 20 possible buffers, instead of allocating memory space at run-time.
 - Because of this, I wanted heap allocation for strings. I can ask for shorthand form (CAPT25), then allocate heap space and store it there.
 - The use of FORTH words allow for two forms: "CAPT25" and the expansion into a string, for final printing "Captopril 25mg" (along with other minor details).
 - The use of a shorthand is nice because (hopefully) I'll do some spellchecking (no idea on how - however, the shorthand form being a bonafide FORTH worth, hpefully I can figure out a way for the FORTH engine to bork at a wrong spelling).
 - A data structure, such you linked lists, would be nice because I could keep track of the strings that were "converted" to heap mempory (via Julian's SAVE-MEM)

 That format works, because: 1) Patient record is simply the name of a colon definition; 2) everything else in the prescription is a FORTH word too.

 Writing a comma-delimited file would not add functionality. At least, I don't see why it would. Also, writing in those extra quotes would be something that eventually gets in the way. What I need is something that is *extremely* compact, down to the very minimal. 

 We need to write a lot of stuff down, all the time (that's why doctors' handwriting is notoriously bad, BTW), whether it be prescriptions, or filing epidemiological reports, legal reports, etc. Right now, what I have boils down to minimal writing. 

 I'm just trying to figure out ways to accept a valid FORTH statement, such as "CAPT25 30P 1XD" and: 1) allocate heap for it (done - thanks, Julian); 2) retrieve it for later (possible, but must keep track of stuff - for instance, a hash table that has CAPT25 as the keyword, and then keeps the other data (which would be in the form "c-addr u" for every item).

 It's been suggested that I use an execution token of, say, CAPT25 in order to generate the hash key. I think I understand that...I suppose the person meant using vectored execution...But then what about the "c-addr u",  fruits of dynamical heap allocation (remember, that problem began when I found out PAD kept allocating the same addresses)?

 In the case of your list package, for instance, the could the structure support something like (the representation bellow  being NODE1->NODE2->NODE3 etc)? (Suppose the prescription lines: "CAPT25 30P 1PD", next line "SIMVA20 30P 1PN" - this last one Simvastatin 20mg 30 pills 1 pill at night, BTW.)

  CAPT25->c-addr1->u1->c-addr2->u2->c-addr3->u3---->SIMVA20->etc...

 I really couldn't figure out list traversal in your documentation. Also, it seems I have to know the node count, in order to move a new item to the linked list? Is that right?

 I'm not sure a linked list would be the best data structure...

 TIA,
