Custom DE Domain Block - uEngine Other Script Languages or C/C++ lack Block Level integration, or similar abstraction with the Modeling Environment.

Script Language – Ten Instructions Mnemonic Description DEF Define or declare a memory LBL Label used by other instructions END Stops current thread, removes from Thread Queue ACT Action instruction, with expressions and modifiers for input, output, wait, scheduling JIT Jump if True, if expression is true, then jump based on LBL, +/- integer (relative), or absolute JIF Jump if False, if expression is false, then jump based on LBL, +/- integer (relative), or absolute WHL While (true), execute next set of instructions till RTN command reached, else jump LBL, +/- integer (relative) SBR Execute Subroutine, jump based on LBL, +/- integer (relative) RTN Return from SBR or WHL statement, 32 levels supported GTO GOTO specific address, based on LBL, +/- integer (relative), also generate model threads
