SUMMARY
The following command can be used to fill in an enclosed polygon:
PAINT (x,y), pat, border
In this case, x and y represent screen coordinates inside the polygon; the figure is drawn in a color specified by "border" and the variable "pat" may be either an integer or a character string. If "pat" is an integer, the fill is done with a solid color. But if "pat" is a string value, it represents a fill pattern.
A string value for "pat" works correctly in the QB.EXE environment whether the string value is a fixed-length string or a variable-length string. However, the compiled .EXE version of such a program produces an "Illegal function call" error when "pat" is a fixed-length string.
This design limitation applies to QuickBasic Versions 4.00, 4.00b, and 4.50, to Microsoft Basic Compiler Versions 6.00 and 6.00b for MS-DOS and MS OS/2, and to Microsoft Basic PDS Version 7.00 for MS-DOS and MS OS/2.
