Overview

VecStr is an object designed to use for a one dimensional array of string objects.  It can be used to stored a list text data, in which each record is separated by terminated characters.  In MS Window, terminate characters are RETURN (ASCII 13) followed by NEWLINE (10).  In Unix, it is a NEWLINE character.  In MAC OS it is a RETURN character.  VecStr can be used to read and store a non-standard format data.  Then the interesting data can be later on extracted, by using all sorts of string manipulation techniques.

The "pushback" function is, most of the time, used for input data into a vector object.

Member data

Operator

plus (+)       concatenate two vectors                       e.g.      v3 = v1 + v2

minus (-)     subtract one vector from the other          e.g.      v3 = v1 - v2

and (&)       find intersection of two vectors               e.g.      v3 = v1 & v2

or ( | )         find union of two vectors                        e.g.      v3 = v1 | v2              

Construction function

{VecStr} ret  =  VECSTR([{int} argm1])

argm1 = max no of data in the vector    (default = 1)

Example:

Lfunction

object({int} argm1)   =  {String} left-value

argm1 = vector index

Example:
