Syntax:	SETSUBSTR	[ variable ] = [ string ] [ substr ]
Arguments:	[ variable ]	Variable to assign; if the variable does not previously exist it is created.
	[ string ]	Variable or string defining the value of string from which to obtain the delimiter count.
	[ substr ]	Variable or string defining the delimiter string to search for within [ string ]. A delimiter can be one or more characters in length.
Options:	None

This script command searches [ string ] for occurences of [ substr ] and saves the number of occurences found in [ variable ].

The following example uses SETSUBSTR to determine if a filename has no extension:

SET filename = "MyData"

SETSUBSTR dots = filename "."

IFNUM= dots 0 GOTO no_extension

The following example finds the number of file name segments:

SET filename = "data.temporary.sbc.xml"

;; find how many "." occur

SETSUBSTR dots = filename "."

;; the number of segments is one more than the number of dots

SETNUM segments = dots + 1

The SETSUBSTR command can be used to detect and remove unwanted characters (see: Rename files during download) from the names of files to be downloaded. The SETEXTRACT and SETRIGHT commands are also useful for parsing a filenames.
