Print the current picture. The current picture is transformed into a
printable file. The file type is defined according to the extension of the
file name i.e.
Do HELP META for details about the metafile types. Note that a new picture is automatically created for each new plot if the OPTION ZFL1 is on.
For gif files, the picture in memory is not used. The gif file is a direct "hardcopy" of the window number 1 content. The WIDTH and HEIGHT parameters allow to scale the gif output file.
If FILE=HIGZPRINTER or FILE=' ' the PostScript file paw.ps (-111) is generated and the operating system command defined by the environment variable HIGZPRINTER is executed.
The environment variable HIGZPRINTER should be defined as follow:
On UNIX sytems:
or
On VAX/VMS sytems:
Note that if the environment variable HIGZPRINTER is not defined the file paw.ps is created but not printed.

| PNAME | C | Picture name |
| CHOPT | C | Options D='M' |
CHOPT:
| 'M' | Make a new picture in memory with name PNAME. An empty structure is created in memory and becomes the current picture. If PNAME = ' ', the picture is automatically named as PICTnnn, where the starting value of nnn is either 0 (default), or the value assigned by SET to the parameter PICT. |
| 'D' | Display the picture PNAME in memory. |
| 'S' | Scratch the picture PNAME from memory. If PNAME = ' ' the current picture is scratched. |
| 'N' | The picture following the current picture in memory becomes the current picture. If the current picture is the last one in memory, the first picture in memory becomes the current picture. |
| 'L' | Give the list of the pictures in memory, following the sequence of their storage in memory. |
| 'F' | The First picture in memory becomes the current picture. |
| 'P' | Print the picture data structure. Useful to debug programs. |
