| Usage / DISPLAY ARRAY control instructions | |
The language provides several built-in functions and operators to control a DISPLAY ARRAY statement.
You can use the ARR_CURR(), FGL_SET_ARR_CURR(), ARR_COUNT(), SCR_LINE() or SET_COUNT() built-in functions to keep track of the relative states of the current row, the program array, and the screen array or to access the field buffers and keystroke buffers.
