SYNOPSIS
|
|
find_type()
|
|
x String to find
|
|
lib TYPELIB (struct of pointer to values + count)
|
|
full_name bitmap of what to do
|
|
If & 1 accept only whole names
|
|
If & 2 don't expand if half field
|
|
If & 4 allow #number# as type
|
|
|
|
NOTES
|
|
If part, uniq field is found and full_name == 0 then x is expanded
|
|
to full field.
|
|
|
|
RETURN
|

-1 Too many matching values
|
|
0 No matching value
