- Data is stored into STM using the READ and ADD commands. Data isì
- further manipulated in STM using the BIND, UNBIND, and COMPUTEì
- commands. The BIND command simply assigns a value to a variableì
- name, and the UNBIND command removes that assignment and leavesì
- the variable in STM with no associated value. The COMPUTE comì
- mand is useful for doing simple calculations, string manipulationì
- and list operations.
- ì
- Data is output from STM using the WRITE command. When using theì
- WRITE command for display output, you can optionally write a new-ì
- line (skip a line on the screen), clear the screen, randomlyì
- position the cursor, and draw boxes on the screen.
- ì
- The STM command RUN is used in those special situations whereì
- complex calculations or other special manipulation of data needsì
- to be done. You may execute an external program which wouldì
- perform the desired operations, and store the result in an diskì
- file. This file could then be read into STM using the READì
- command, and subsequent rules could be executed based on thisì
- data.
