 +The VC12FndYPnt function __calculates the y-coordinate of a point to a line__ According to 2 points of the same line(X1-Y1 and X2-Y2) and the x-coordinate of point (XP).

 +===== IMPLEMENTATION =====
 +
 +**VC12FndYPnt (pointX1,  pointY1, pointX2, pointY2, pointXP, pointYP)**
 +
 +Parameters:
 +
 +^IN/OUT^VARIABLE TYPE^EXAMPLE NAME^DIM^^
 +|  IN  |  SYSTEM or GLOBAL  |  pointX1  |  L/S  |Point X1 of the straight line (Abscissa X1)|
 +|  IN  |  SYSTEM or GLOBAL  |  pointY1  |  L/S  |Point Y1 of the straight line (Ordinate Y1)|
 +|  IN  |  SYSTEM or GLOBAL  |  pointX2  |  L/S  |Point X2 of the straight line (Abscissa X2)|
 +|  IN  |  SYSTEM or GLOBAL  |  pointY2  |  L/S  |Point Y2 of the straight line (Ordinate Y2)|
 +|  IN  |  SYSTEM or GLOBAL  |  pointXP  |  L/S  |Point X of the straight line for which you want to calculate the abscissa (Y)|
 +|  OUT  |  SYSTEM or GLOBAL  |  pointYP  |  L/S  |Point Y of the straight line calculated by the function (Unknown ordinate)|
 +
 +N.B.: pointX1, pointY1, pointY1, pointY2 between them must be the same size (DIM). All parameters must be the same type (SYSTEM or GLOBAL)
 +
 +=== Example ===
 +
 +Execute the calculation when the  "gfCalc" flag is set to 1.
 +
 +<code QCL>
 +IF gfCalc
 + gfCalc = 0
 + pointX1 = 100 ;Sets the point values of the straight line
 + pointY1 = 600
 + pointX2 = 200
 + pointY2 = 1200
 + pointXP = 150
 + VC12FndYPnt (pointX1,  pointY1, pointX2, pointY2, pointXP, pointYP)
 + gsAscissaCal = pointYP
 +ENDIF
 +</code>
 +
 +=== DIFFERENCES FROM THE OLD RELEASE ===
 +
 +  * (from 10 to 11) Added the possibility to declare "pointXP" and "pointYP" parameters with Long dimesion (L)
 +  * (from 11 to 12) Introduced the possibility to use GLOBAL type parameters.
