SEND VARIABLE


SEND VARIABLE ( variable )

Parameter	Type	Description
variable	Variable	Variable to send

Description

SEND VARIABLE sends variable to the document or serial port previously opened by SET CHANNEL. The variable is sent with a special internal format that can be read only by RECEIVE VARIABLE. SEND VARIABLE sends the complete variable (including its type and value).

Notes:

If you send a variable to a document using this command, the document must have been opened using the SET CHANNEL command. You cannot use SEND VARIABLE with a document opened with Open document, Create document or Append document.
This command does not support array variables. If you want to send and receive arrays from a document or over a serial port, use the BLOB Commands.

Example

See example for the RECEIVE RECORD command.
