1.19 READ: Read lines in file (as from SW 5.2)
810D 840Di
Error variable for return (call-by-reference parameter, type INT)
0 No error
1 Path not allowed
2 Path not found
3 File not found
4 Incorrect file type
13 Insufficient access rights
21 Line not available (parameter "line" or "number" larger
than number of lines in file)
22 Array length of "result" variable too small
23 Line range too large (parameter "number" has been selected so
large, that reading goes beyond the end of the file)
Name/path of the file to be read (call-by-value parameter of type
STRING with a max. length of 160 bytes). The file must be stored in the
user memory of the NCK (passive file system). The file name can be
preceded by the domain identifier _N_. If the domain identifier is
missing, it is added correspondingly.
The file identifier ("_" plus three characters, e.g. _SPF) is optional. If
there is no identifier, the file name is automatically added _MPF.
If there is no path specified in "file", the file is searched for in the current
directory (=directory of selected program). If a path is specified in "file",
it must start with a slash "/" (absolute path indication).
Position indication of the line range to be read (call-by-value parameter
of type INT).
0 The number of lines before the end of the file
which is specified by the parameter "number" is read.
1 to n Number of the first line to be read.
Number of lines to be read (call-by-value parameter of type INT).
Array of type STRING, where the read text is stored
(call-by-reference parameter with a length of 255).
