 +====== VI11WaitBufferReadyUsingWAIT ======
 +
 +**V = **//Vector//
 +
 +**I = **//Image//
 +
 +Function that is used to manage the Vector Image feature (object that resides on some versions of Qpaint).
 +
 +The VI11WaitBufferReadyUsingWAIT function is __used to wait for the conclusion of the design phase was started__.\\
 +A Wait instruction inside causes the statement following the line of calling this function, be done only when the design phase on the Vector Image is permanently closed.
 +
 +===== HISTORY =====
 +
 +The VI11WaitBufferReadyUsingWAIT function replaces the previous [[.:VI10WaitBufferReadyUsingWAIT]] making the non-blocking flow of execution in case the condition to check is true; If the check condition is fails, then the instruction is executed to WAIT.
 +
 +===== IMPLEMENTATION =====
 +
 +**VI11WaitBufferReadyUsingWAIT (awBuffer)**
 +
 +Parameters:
 +
 +^IN/OUT^VARIABLE TYPE^EXAMPLE NAME^DIM^^
 +|  IN  |  ARRSYS /\\ ARRGBL  |  awBuffer  |  W  |Array that serves as a buffer for instructions/data|
 +
 +=== Example ===
 +
 +//TASK_00//
 +<code QCL>
 +MAIN:
 +      
 +VI11WaitBufferReadyUsingWAIT( awBuffer )    ;Awaits the conclusion of the previous design
 +...
 +VI10DrawBuffer( awBuffer )    ;Draws the contents of the Buffer
 +
 +glPippo = 1000                            ;(This instruction runs only at the end of the design process)
 +</code>
 +
 +=== Note ===
 +
 +  * This function contains the WAIT. Not for use in a task that requires the full implementation of the instructions at each cycle.
