Block

A block is made up of words.

The blocks are separated by characters s (Line Feed) in the memory. The use of a block number is not mandatory in the blocks. To distinguish the end of block from the beginning of another block on the screen, each new block begins in a new line, with a character > placed in front of it, in the case of a block longer than a line, the words in each new line are begun with an indent of one character.

Main Program and Sub-program

The part programs may be divided into two main groups - main programs, and

subprograms.

The procedure of machining a part is described in the main program. If, in the course of machining repeated patterns have to be machined at different places, it is not necessary to write those program-sections over and over again in the main program, instead, a sub-program has to be organized, which can be called from any place (even from another sub-program).
