 +The VC12FndXPnt function __calculates the x-coordinate of a point to a line__ with 2 points of the straight line (X1-Y1 and X2-Y2) and the y-coordinate of the point (YP).

 +===== IMPLEMENTATION =====
 +
 +**VC12FndXPnt (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)|
 +|  OUT  |  SYSTEM or GLOBAL  |  pointXP  |  L/S  |Point X of the straight line calculated by the function (Unknown abscissa)|
 +|  IN  |  SYSTEM or GLOBAL  |  pointYP  |  L/S  |Point Y of the straight line for which you want to calculate the abscissa (X)|
 +
 +N.B.: pointX1, pointY1, pointY1, pointY2 between them must be the same size (DIM). All parameters must belong to 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
 + pointYP = 1000
 +        VC12FndXPnt (pointX1,  pointY1, pointX2, pointY2, pointXP, pointYP)
 +        gsAscissaCal = pointXP
 +ENDIF
 +</code>
 +
 +=== DIFFERENCES FROM THE OLD RELEASE ===
 +
 +  * (from 10 to 11) Added the possibility to declare parameters "pointXP" and "pointYP" with Long dimension (L)
 +  * (from 11 to 12) Introduced the possibility to use GLOBAL type parameters
