Format expressions

The format expression allows you to print data anywhere on the terminal, quickly and easily clear portions of the screen, and highlight characters in a number of different ways.

The syntax of this expression is:

  @([column,row,][command][,command...])

where

• "column" is the terminal column to start printing
• "row" is the terminal row to start printing
• "command" is a format subcommand:
  • See CLREOS and CLREOL,
  • See BOLD, BLINK, REVERSE, UNDER, ALLOFF, or
  • See RFIELD

The cursor position (column,row) is optional. If it is present, both column and row must be specified. If it is not present, the current cursor position is used.

Example:

   PRINT@(10,5)           move cursor to column 10, row 5
   PRINT@(1,1,BOLD)       home cursor, switch bold attribute on 
   PRINT@(CLREOL)         clear from cursor to end of line
