PickBASIC / FlashBASIC

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.
