Distributed with NCAR graphics is a set of
user entries that will
perform the setting of the escape data records and call the GKS
escape function. An escape function relevant to NCAR GKS
has meaning only in NCAR GKS, and not in any other GKS packages.
You should use the entries
NGSETI, NGSETR, or NGSETC to
make your escape calls. See the man pages for those utilities
(which exist only in Version 4.0 or later). See also the man
page for ngmisc_params which describes all of the available
parameters. Here is a summary of the escape functions that
exist in NCAR GKS:

| | | ngmisc
# | Description | Notes | param.
---------------------------------------------------------------------------
-1386 | Flag whether clipping rectangles in segments | | IC
| are transformed by the segment transformation | |
-1387 | Temporarily close an NCGM. | ncgm only | none
-1388 | Set/save/restore primitive attribute settings | | none
-1389 | Reopen an NCGM for appending. | ncgm only | none
-1390 | Returns 'NCAR_GKS0A--VERSION_4.0' in ODR | | none
-1391 | File name to be used for the next opened file | | ME
| (using GOPWK) of category MO. | |
-1393 | Picture name for the next picture. To name the | ncgm only | PI
| first picture, call this escape before opening | |
| the workstation. | |
-1394 | Sentinal characters for creating segment names.| | SE
-1397 | Flags whether segments will be deleted when | | SS
| WISS is closed. Default is to delete them. | |
-1398 | Specify maximum number of GKS error messages | | ER
| to issue before aborting. Default is ten. | |
-1399 | Flag to indicate if clipping to the NDC | | CL
| viewport is on. The default is yes (incurring | |
| about an 8% overhead. | |
-1400 | Specifies the error allowed in matching the | X11 only | PE
| requested colors, expressed as a percentage. | |
| Default is 10. | |
-1401 | Tells the X driver to specify its own color | Obsolete | PR
| map rather than sharing with other windows. | |
| This is identical to specifying 1 for the | |
| color model with escape -1402. | |
-1402 | Tells the X driver which color model to use. | X11 only | SC,MC,
| First integer is the workstation id. If -1 is | | PC
| used, the escape will apply to the next | |
| workstation created. The second integer | |
| specifies the color model to use: | |
| 0 = shared X colormap | |
| 1 = private X colormap | |
| 2 = mixed model-use shared as long as possible | |
-1512 | Specify spacing between software fill lines. | PS only | FI
-1513 | Specify spacing between hatch pattern lines. | PS only | HA
-1514 | Maximum size of the operand stack. | PS only | ST
-1515 | Maximum number of points in a path. | PS only | PA
-1516 | Scale factor for nominal linewidth. | PS only | NO
-1517 | Specifies whether background color will | PS only | FU
| fill the entire page or just the viewport. | |
| Default is viewport. | |
-1518 | Specify type of line join. Default is "round". | PS only | JO
-1519 | Specify type of line cap. Default is "round". | PS only | CA
-1520 | Specify miter limit of line joins. Default | PS only | MI
| Default is 10. | |
-1521 | Coordinate points for positioning output. | PS only | LX,LY,
| Default is largest square on output device. | | UX,UY
-1522 | Scale factor for representing coordinates. | PS only | CO
-1523 | Flag for selecting RGB or CMYK color model. | PS only | CO

for details on escape functions that apply specifically to X output workstations, see X11 escapes.
For details on escape functions that apply specifically to PostScript output workstations, see PostScript escapes.
If you invoke an escape function that applies to a specific workstation type, it will have no affect on any of the other workstation types.
