Improving Problem-Oriented Language by Stratifying It
The Mitre Corpn., Bedford, Massachussetts, USA
In order to lighten the programming task, further development of problem-oriented computed languages must take the direction of relieving the programmer of specifying those details which in theory can be supplied mechanically. The first step toward accomplishing this is to develop programming languages which permit the mechanically-supplyable expressions to be stated separately from the remainder of the program expressions. An immediate benefit of this first step is that the programmer is free to formulate, express, and modify procedures and data for the solution of a problem without concern for the manner in which the procedures and data will be implemented on a computer. By having the mechanically-supplyable detail separately stated, the way is paved for the development of translating programs which can supply this detail. These ideas are not radically new, but rather serve to emphasize a trend which is apparent in current computer languages but which has not been carried far enough.
