zva

An integer describing the current position of the parse input.

poi

The parse input, as a specially formatted string. (See make-lerfu-porsi-string and make-lerfu-porsi-port.)

Create a lerfu-porsi from the integer index zva and the parse input poi. poi is specially formatted, and must come from calling make-lerfu-porsi-string or make-lerfu-porsi-port. It has an appended character acting as a "sentinel" for purposes of detecting the end of the input buffer.

zva must be less than or equal to the string-length of poi.
