Structure Editor : File Formats : JSP Tool

This format was used by the JSP Tool application produced by IDK Data & LBMS. It is divided into a number of PROCESS sections, each of which has an OPERATIONS list, a CONDITIONS list, a QUITS list, and a DIAGRAM section. In addition each process and the program as a whole can have a free-text header and trailer.

The DIAGRAM section is a composed of the following columns :-

box number
parent box number
x co-ordinate (JSP Tool writes logical position, the Structure Editor writes pixel position)
y co-ordinate (JSP Tool writes logical position, the Structure Editor writes pixel position)
side-effect ('B' for none, '+' for intolerable, '-' for benificent)
box type ('B' for sequence, '*' for iteration, 'o' for selection)
box sub-type ('B' for normal, 'P' for posit(er), 'A' for admit, '&' for quit, 'U' for until)
condition ID (or '0' for no condition)
box name (unless its a quit or leaf node in which case the quit condition or operation list is on the sunsequent row)

Below is a an example of a JSP Tool format structure file (in this case containing 'C' code) :-

/* This program prints out a table of Fibonacci numbers. 
   These are defined by a series in which any element is
   the sum of the previous two elements. The program 
   stores the series in an array, and after calculating
   it, prints the numbers out as a table.
