writetx statement

The writetx statement writes a tape record, converts the string from ASCII hex to binary, and copies the string to the tape buffer.

Syntax

 writetx var[then|else|onerr statement.block]

Description

The length of the tape record is specified by the most recently executed TCL t-att command.

  • The then clause is taken if the operation is successful.
  • Either else or onerr can be specified, but not both.

    If the tape unit has not been attached or if an end-of-file (eof) mark is read, the else or onerr clause, if present, is executed. In addition, the onerr clause can be used to check for end-of-tape (eot), tape unit not ready, parity error, or block transfer error.

Note: If a writetx is attempted without a device attached, BASIC takes the else clause with system(0) = 1, but FlashBASIC attempts the write.
