TXT.flw
TXT.Find_Line_with
Search a Text in the TXT.-internal Buffer and return Line-Number and Byte-Position where it was found.
Intention
This is the simple search, it will just return the most needed results.
This command is used to get the Line-Number and Byte-Positions of a Search-String,
that was found in the Text that is in the Internal TXT-Buffer, into Variables.
As slightly faster Alternative to TXT.flw, this command will return all needed Information to replace the text or work with it in any way.

If you use the command without Output-Variables, the result will be on the stack in reverse order.
TXT.flw|$$SEA
What you see here is:
TOS: Byte-Position of found Text in whole Text
TOS+1: Line-Number where the Text was found
Syntax
TXT.flw|P1[|P2][|P3][|P4]
TXT.Find_Line_with|P1[|P2][|P3][|P4]
Parameter Explanation
P1 - (Input) Variable with String to search for.
P2 - (numeric) Variable will contain a number or 0, this the Starting-Line for the search. The search will at the first byte of the Line.
If this is 0 or 1, the complete loaded Textfile will be searched.
P3 - (Output) Variable will contain the Line-Number of the Line that contains the Search String.
If omitted, the result is placed on TOS.
P4 - (Output) Variable will contain the Byte-Position of the fist-Byte of the Search string in the Text.
If omitted, the result is placed on TOS.
