Description

The FGETS() function reads and returns a line of text from the file specified by <expN>, an ASCII file handle. The file handle is returned from the FCREATE() or FOPEN() functions. The FGETS() function reads a line of text from the current position of the record pointer. You may optionally specify the number of bytes to read from that point with the numeric expression <expN2>. The number of bytes may be from 0 to 254. If a number is not specified, the FGETS() function will read 254 bytes or to the end line marker. The optional character expression <expC> defines an end of line terminator to determine where the FGETS() function will stop reading. The character expression <expC> must evaluate to one or two characters.

Example

fp = fopen("names.txt")
count = 0
do while not feof()
    if fgets(fp,20) = "Smith"
        ++count
    endif
enddo
