This texture will remain in effect until:

• An END is given within the current file
• The file in which the START is located ends
• A STEP command is reached

The texture will remain active when processing an included file unless overridden within that file.

The END command stops using the current texture and restores the previous texture to current status. This means that nested commands with START will form a stack of textures and the END command will pop those textures. However, END cannot appear in a different file from START. If an END command is given in a sub file without a START having been given in that same file, the END stops the use of a texture specified in a calling file, then that texture will be restored to use when the sub file is exitedhas no effect.
