Method of storing and printing image with non-reentrant basic disk operating system

DETAILED DESCRIPTION What is claimed is: 1.
A method for storing and printing an image utilizing computer graphics apparatus of the type having a non-reentrant operating system comprising the steps of: A.
requesting the computer graphics apparatus to save bit mapped image data for a selected image on an external data storage medium; B.
determining whether the operating system is active and holding further action pursuant to said image save request if the operating system is determined to be active; C.
determining at the end of each period in which the operating system is active whether an image save request was made during that period of operating system activity; D.
saving said bit mapped image data on the external storage medium either immediately in response to said image save request upon the determination in step B that the operating system is not active or after the termination of operating system activity in response to the determination in step C that said image save request was made during a period of operating system activity; and, E.
printing the image from said bit mapped image data stored on said external storage medium.
2.
The method of claim 1 wherein said operating system is a basic disk operating system.
3.
The method of claim 2 wherein said bit mapped image data is saved in step D immediately after the period of basic disk operating system activity during which the image save request of step A is made.
4.
The method of claim 3 wherein said computer graphics apparatus includes an image display having more than one display terminal and further including the steps of determining what image display terminal is active.
5.
The method of claim 4 further including the steps of opening a window within said active image display terminal, answering a plurality of questions displayed in said window so as to positively designate said image to be saved and thereafter closing said window prior to saving said bit mapped image data in step D.
6.
The method of claim 5 further including the step of opening another window within said active image display terminal, reporting the status of the bit mapped image data saved and thereafter closing said other window subsequent to saving said bit mapped image data in step D
