Programming SYSTEM-90E is intuitive and straightforward. Both simple operations
for processing integer variables, floating point variables, positions etc. (operands) and more
complex functions such as sine, cosine, log, etc. can be performed using only a small number of instructions.

| |
| Effective programming |
|
Each instruction is composed of a single operation and one or two operands. In effect, operations and
operands can be randomly combined within an instruction. The result is easy yet very effective programming.
|
| |
| Symbolic instructions |
|
Programming may be done using symbols, i.e., all variables, constants and resources can be designated by name.
An assembler assembles these names into a language which the central processor is able to process. In this way
it is possible to create and document programs conveniently and coherently.
|
|
A complete process may thus be implemented using only a few instructions.
