# Description

The statement is used to terminate a read statement when no data has been read in a specified time period. It takes the general from:

TIMEOUT file.variable,Time
1

Where:

file.variable specifies a file opened for sequential access.

time is an expression that evaluates to the number of seconds the program should wait before terminating the READSEQ statement.

TIMEOUT causes subsequent READSEQ and READBLK statements to terminate and execute ELSE statements if the number of seconds specified by time elapses while waiting for data.

If either file.variable or time evaluates to null, the TIMEOUT statement fails and the program enters the debugger.

An example of use is as:

OPENSEQ "SLIPPERS" TO FILE_VAR ELSE ABORT 201
TIMEOUT FILE_VAR, 10
READBLK VAR1 FROM SLIPPERS, 15 THEN CRT VAR1 ELSE
    CRT "TIMEOUT OCCURRED"
END
