## Syntax

    txt = mgetl(file_desc [,m])

## Arguments

## Description

`mgetl` function allows to read a lines from an text file.

If `m` is omitted or is `-1` all lines till end of file occurs are read.

If `m` is given `mgetl` tries to read exactly `m` lines. This option is useful to sequentially read part of a file. In this case if an end of file (EOF) occurs before `m` lines are read the read lines are returned (it is possible to check if EOF had occurred using the `meof` function) issued.

`mgetl` allows to read files coming from Unix, Windows or Mac operating systems.

`mgetl` supports only UTF-8 and ANSI file encoding.

## Examples

    mgetl('SCI/etc/scilab.start',5)

    mgetl SCI/modules/elementary_functions/macros/erf.sci

    fd=mopen('SCI/etc/scilab.start','r')
    mgetl(fd,10)
    mclose(fd)
