- get a string from a file

File Input/Output functions
(AmiBroker 4.50)

SYNTAX fgets( filehandle )
FUNCTION The fgets function reads a string from the input file (defined by filehandle argument ) and returns it as a result.

fgets reads characters from the current file position to and including the first newline character, or to the end of the file whichever comes first. The newline character, if read, is included in the returned string.

The filehandle argument is a number returned by fopen function. The file has to be opened with "r" flag (for reading).

NOTE: fgets() reads maximum 1024 characters per line. Lines longer than that can be read using sequential calls to fgets() and "adding" (concatenating) results.
