Purpose
Function to write a character expression to an ASCII file
Syntax
FWRITE(<expN1>, <expC>[, <expN2>])
See Also

Description
The FWRITE() function writes the character expression <expC> to a specified text file. The <expN1> is the file pointer returned by either the FOPEN() or FCREATE() functions. The optional <expN2> specifies the maximum number of bytes to write from the buffer.
If an error occurs during the operation -1 is assigned to the FERROR() function. The file pointer must be assigned when the file is first opened using the FOPEN() or FCREATE() functions. FWRITE() does not include line terminators when writing to the file; this can be achieved using FPUTS().
Example
fp=fcreate("time.txt") if ferror()=-1 dialog box "The file could not be created." else fwrite(fp,timestamp()) endif fclose(fp) if ferror()=-1 dialog box "The file could not be closed." endif
Products
Recital Server, Recital
