I'm still not understanding your syntax. I understand targ means target or the part of the string, what I call FILE, with the 10 CHR (line feed character). Also, len means length, or the SIZE of FILE. What is new? Is it the replacement for targ?

I can't figure out how to use C$ n. I get 'C$ n' on the stack when I use it. I wrote STORE to remove the line feed (LF) characters from the FILE string. It made sense to:

(1) Find the first occurrence of the LF character
(2) Remove the string preceding the LF character, store it in PNTS
(3) Store the string proceeding the LF character, to be used in subsequent loops
(4) Exit the loop when no more LF characters are found

I ended up:

(1) Storing the position of each LF character
(2) Using that position and the FILE length (SIZE) to remove (SUB) the remaining part of FILE
(3) I added (STO+) subsequent positions to a variable until I reached a point where POS
returned a zero

Please note that all substrings will not be of equal lengths, because some coordinate pairs will have point numbers containing 1 to 5 digits. Also, an actual coordinate file will be in the form of P,N,E,Z,D (e.g., 208,1531217.411,520676.455,98.393,IRC 1/2 LB 6300) where:

P is the point number
N is the northing
E is the easting
Z is the elevation
D is the description
