Flow (CAOS)

Flow is a concept in coding which determines the order in which instructions are read and executed by the computer, similar to the order of operations in mathematics (see wikipedia:Control flow). Flow involves conditionals and subroutines, or may allow the selection of a certain TARGet object.

In CAOS, commands which are used to control the execution flow of commands include:

C1

Routine and coroutine

• STOP
• ENDM
• SUBR
• GSUB
• RETN
• INST
• WAIT

Iteration

• REPS
• REPE
• LOOP
• UNTL
• EVER
• ENUM
• NEXT

Random sampling

• RTAR
• RNDV

Conditional

• DOIF
• ELSE
• ENDI

Arithmetic

• ADDV
• SUBV
• MULV
• DIVV
• MODV
• NEGV
• ANDV
• ORRV

Debug

• DBUG
• DBGM - in prerelease versions of C1

C2

In Creatures 2, ESEE and ETCH were added to work in pairs with NEXT, as were STAR, ESCN and its closing NSCN.

C3/DS

GOTO and ELIF were added.
