A couple of pointers.
--> FIND/MATCH
Will allow you to match the beginning of the line.
--> PARSE
Is I think possibly a better solution for dealing with the lines.
If line is one of your example lines (of type string!) then you could try:
parse line none
parse line "$,"
parse next line none
If these work in all cases (you'll need to check if all the possible
characters output by
the GPS are handled by these lines correctly), then you might be able to
SELECT
a block of variable names by using the first code. Then you might be able to
SET
them all at once with the result from "parse next line none".
Or alternatively define some parse rules that "recognise" the various actual
line formats.
Just ideas, maybe one will be useful :)
