Skipping and Searching
Any characters that lie outside of a format directive are used as Òread throughÓ char-
acters. More sophisticated searching can be done using the %x (or %X) directive.
When a %x is encountered in the format string, text is popped from the stack, and the
source is searched for a matching string. If one is found, the empty pointer is moved
past it. Thus, the LPL code
&y "END=" &x "%d%x%f" file
ENTER
will do the following steps: 1) read an integer, assign it to x. 2) consume characters
until the string ÕEND=Õ is consumed. 3) read a floating point value, assign it to y.
User Defined Radix
If the source contains numeric values that are not decimal, they can be read and con-
verted using the user defined radix type code ÕrÕ. The character immediately following
the ÕrÕ determines the radix, or base, to be used. This character should be the highest
value character in the base. (binary = Õ1Õ, decimal = Õ9Õ, hex = ÕfÕ, base 36 = ÕzÕ, etc.)
For example, if a file contains the following line
ff ef 8e 01101101
and we wished to interpret these as 3 hex and 1 binary value, and store them as 4 in-
teger variables (a, b, c, and d), we would write
&d &c &b &a "%rf %rf %rf %r1" file
