bcad_label

BricsCAD uses a genuine multi-column control for listboxes.
As a result it is possible to have resizable columns and real column labels.

The DCL engine tries to detect single-line column labels in the label attribute of legacy DCL code.
To specify single- or multi-line column labels, the bcad_label attribute can be used.

This attribute specifies the column labels of a multi-column ListBox; column labels can be separated by tab "\t" or by vertical bar "|".

Within the column label text, newlines "\n" may appear to specify a multi-line column label.
The BricsCAD DCL engine can also detect column labels from the label attribute.

If both the label and bcad_label attribute are specified, bcad_label will be used instead of label.
When using the bcad_label attribute, the plain label attribute can be specified as an alternative on other DCL engines.
