I'm annoying for execution results

long row
int col, oldcol, ret
row = getrow ()
oldcol = this.getcolumn ()
IF row <1 THEN
return 0
END IF
FOR col = 1 TO 1000
ret = this.setcolumn (col)
IF ret = -1 THEN
this.setcolumn (oldcol)
return col-1
END IF
NEXT

If there is no row with focus in the data window, return 0;
If there is a row with focus, the column number of the last column (col-1) is returned, and the focus is still set on the original column.If the number of columns is greater than 1000, there is no return value, and the focus is set to the 1000th column.

The landlord seems to be doing the problem.

Brothers come for a detailed explanation
Because I do n’t know about PB, I asked a friend

long row
int col, oldcol, ret
row = getrow () // Get the current row of the data window (the row with focus)
oldcol = this.getcolumn () // Get the ordinal of the current column
IF row <1 THEN // Return 0 if there is no row with focus
return 0
END IF
FOR col = 1 TO 1000
ret = this.setcolumn (col) // Set the col column as the current column
IF ret = -1 THEN // Return -1 setting error
this.setcolumn (oldcol) // Set the current column to the original column
return col-1 // return the previous column of the error column
END IF
NEXT

IF ret = -1 THEN //this.setcolumn(col) returns -1 to indicate that the focus was set incorrectly

The code is simple, but, you have to say when it was written. . . . So as to judge
