Purpose |
Output data to a sequential file in a delimited format. |
Syntax |
WRITE #filenum& |
filenum& |
The file number used when the file or device was opened. |
expression |
A
|
Remarks |
WRITE# is similar to PRINT#,
except WRITE# inserts a comma in the output file between each expression.
It encloses
WRITE# is the preferred method of writing data to a sequential file, since it formats the output to be readable by the INPUT# statement. In other words, INPUT# respects the delimiter characters that separate items in a line of text, as created by WRITE#. WRITE# with a file number and a comma but no expressions, outputs a carriage return to the file. To read a delimited file without regard to the delimiter characters, use the LINE INPUT# statement. |
Restrictions |
For best results, strings should not contain quotation marks, as these may interfere with the expected output format. Each expression in the WRITE# statement must be separated from other expressions by a comma or semicolon. If you include a trailing comma or semicolon, the final carriage return / line feed is suppressed and replaced with a comma delimiter. This allows you to append data to the sequential record by executing another WRITE statement. |

Example |
' Open a sequential output file and write to it OPEN "FILE.TXT" FOR OUTPUT AS #1 WRITE #1, "TEST" z& = -12345& info1$ = "Do not covet" info2$ = "thy neighbors ox" WRITE #1, z&, info1$, info2$ WRITE #1, "TEST" CLOSE #1 |
Result |
"TEST" -12345,"Do not covet","thy neighbors ox" "TEST" |
