Modify and Copy Labels

A GLAB or SLAB generated by the autotagging process is the same as a conventionally created Label except that its SORF attribute (set to Nulref in the ‘manual’ case) is set to refer back to the controlling TAGR. SORF can be set to Nulref, thus breaking the link between the Label and the TAGR, but it cannot be set to point to another TAGR (or to any other value). Having broken the link, a subsequent UPDATE TAGGING command creates another Label on the labelled Design element.

GLABs or SLABs generated by the autotagging process can be modified, but safeguards are applied to make sure that the Labels always comply with the definition set up by the TAGR:

• The DDNM attribute cannot be changed

• The BTEX attribute cannot be changed (GLABs)

• The TMRF attribute cannot be changed (SLABs)

• The Label cannot be INCLUDED in another Layer

• The Label cannot be deleted

If a Label with its SORF attribute set is copied, the new Label has its SORF attribute set to Nulref.

SORF can be unset by

SORF =0        or

SORF NULREF
