CURPOS$
System variable: CURPOS$ Length: 2 Description: The system variable named CURPOS$ contains the position of the cursor at the last data transmission from the video device. The value is a two-byte hex string containing the cursor position in the form "@YYXX@" where "YY" represents the row and "XX" represents the column plus 1. (The minimum column value is 1 and the maximum is 64, 80, or 132, depending on the screen setting. To arrive at the actual cursor position, you must subtract 1 from the column value.) The CURPOS$ string must be converted as follows to achieve the cursor position in decimal: LENGTH 2 & LOCAL A$ ! Receiving variable for CURPOS$ LENGTH 2.0 & LOCAL X,Y ! Numeric variables for row, column . . . A$ = CURPOS$ ! Contents of A$ will be @YYXX@ Y = HEXDEC(SUB(A$,1,1)) ! Row value (decimal) X = HEXDEC(SUB(A$,2,1)) - 1 ! Column value (decimal)
