CSRLIN

function

✔ Appearance ✔ Standard ✔ Console

Syntax

currentLine = CSRLIN

Description

This function returns the number of the "current" text line (that is, the text line which contains the current pen position) for the current window. The text line at the top of the window is considered Line #0.

CSRLIN does not necessarily reflect the number of text lines which have actually been displayed. It is calculated based on the current pen position and the size of the current font.

Example

WINDOW 1
TEXT _monaco, 16
CLS
FOR i = 1 TO 10
  PRINT "CSRLIN = "; CSRLIN
NEXT

FB Lite behavior:
When you use the "FB Lite" runtime, CSRLIN switches to the Text Window before executing. The value returned is the actual line number in the edit field and remains accurate even when the field is scrolled.
