RLn(N[,X])

The '''RLn''' [[internal function]] returns the record length of an open [[file handle]] N. The optional X parameter may be used with external files only to shorten the record length to the specified amount.

====Comments and Examples====
Here are three quick steps to determine the record length of an internal file from immediate mode (although this could also be a program).

00100 OPEN #1:"name=filename",I,I,S
00200 PRINT RLN(1)
00300 END

The number printed by PRINT RLN(1) is the record length for file 1. The END statement is a short way to close any open files.

In the following example, RLN shortens the record length of file 1 to 128 bytes. It is important to note that RLN can only shorten, not lengthen, external file record lengths.

10 LET RLN(1,128)

For additional information about external file record lengths, see the [[POS=]] and [[REC=]] parameters for the [[READ]] file [[statement]].

*[[File$]]
*[[FileNum]]
*[[FreeSP]]
