Overview

Guide section 12.1 takes a keyboard type and target GET object. Its appendix identifies alphanumeric, numeric and symbol keyboards. Do not confuse this with simulated-keystroke commands in other languages. This subset neither confirms availability in current SmartClient nor assumes constant numeric values. (Sources: refs. 1–1.)
