## GR_SEGM

`GR_SEGM(NAME,ERROR`

Close the current graphic segment and open a new graphic segment with the current plotting attributes selected by `PENCIL`. All the commands of GREG open at least one new segment, but the immediate routines do not. This routine must be called prior to calling a series of immediate routines to ensure that the plot will appear with the currently selected graphic attributes, and to allow a selective erasure of the plot. NAME is a character string indicating the desired name of the segment, and ERROR a logical error flag. All plot request issued between two successive calls to `GR_SEGM` will make a single graphic segment. Note however that every GREG command having an effective plot action creates one or more graphic segments.
