Post Processor Generator for Use With a Photocomposer Composition Program

Described is a post processor generator program that uses a library of incomplete source statements to construct, to input specifications, a program capable of controlling a photocomposer.

There are a number of photocomposers having different fonts, different character sizes and other differing characteristics. If such photocomposers are computer controlled, it is desirable to have a post processor generator which responds to input data which supplies the post processor with information regarding the type of photocomposer, the functions it is capable of performing, and to provide commands to instruct the photocomposer to perform the various functions.

The post processor program is built in blocks of code, as illustrated in Fig. 1. The blocks are assigned to three different functional areas of the post processor, namely:. 1. The main line requirements area as indicated at

2, which provides a means for the post processor

program to communicate with the program internal

to the composition computer. That is, a means

of communication between the post processor and

the host processor.

2. The device function area as indicated at 4, which

sets forth the functions that the particular

photocomposer is capable of performing.

3. The device control area as indicated at 6, which

sets forth the commands for instructing the

particular photocomposer to perform the functions

it is capable of performing, and...
