TESTDATASIZE

of datafiles and convert to dataset

    B = TESTDATASIZE(A,STRING)
   I = TESTDATASIZE(A,STRING,FALSE)
   I = TESTDATASIZE(N)

Input
A	datafile or dataset
STRING	'data' (default) or 'features' or 'objects'
N	Given data size to be tested

Output
B	Converted dataset
I	TRUE: conversion possible
FALSE:	conversion not possible

Description

Depending on the value of PRMEMORY and the size of the datafile A, it is  converted to a dataset, otherwise an error is generated.  In case the third parameter is FALSE or the first is a scalar just a test  is executed. In case of no output arguments an error is generated if  conversion in impossible.

The parameter STRING controls the type of comparison

'data'	PROD(SIZE(A)) < PRMEMORY
'objects'	SIZE(A,1).^2 < PRMEMORY
'features'	SIZE(A,2).^2 < PRMEMORY
