Syntax

CALL SEND (data-vector-id, '_setNumberOfColumns', num-columns<, return-code>);

Argument Type Description

num-columns
N specifies the number of columns in the GET_DATA data vector

return-code
N returns a code that designates whether the _setNumberOfColumns call is successful:

0 successful

<0 unsuccessful

Argument	Type	Description
num-columns	N	specifies the number of columns in the GET_DATA data vector
return-code	N	returns a code that designates whether the _setNumberOfColumns call is successful:
		0	successful
		<0	unsuccessful

Details

The _setNumberOfColumns method is valid if the viewer is a form editor or a table editor.

After the GET_DATA data vector is created, _setNumberOfColumns should be called immediately to tell the _getDATA data vector how many columns that instance refers to. This is necessary because _getData and _setData can deal with more than one column at a time.
