IMMEDIATE ON/OFF
Chapter 2 Program Instructions
Field of Application Statement for enabling or disabling the immediate mode of Intermec
Fingerprint in connection with program editing without line numbers.
Syntax IMMEDIATE ON|OFF
Remarks Before starting to write a program without line numbers, the immediate mode
must be disabled by means of an IMMEDIATE OFF statement. If not, each
line will be executed immediately.
After an IMMEDIATE OFF statement, program lines can be entered without
any leading line numbers. References between lines are done by means of
“line labels”, which are called in GOTO or GOSUB and related statements.
A line label is a name followed by a colon (:). The label must not interfere with
any keywords or start with a digit. When a line is labelled, the line must start
with the line label. When a line label is used as a reference to another line, e.g.
within a GOTO statement, the colon should be omitted.
Before the program is RUN, it should be appended by a IMMEDIATE ON
statement. At the execution of this statement, the program lines will be
numbered automatically in ten-step incremental order, starting with the first
line, i.e. 10-20-30-40-50.... The line numbers will not appear on the screen
before the program is LISTed, LOADed, or MERGEd. Line labels will not
be converted to line numbers.
Do not issue a RUN statement before the IMMEDIATE ON statement, or an
error will occur.
Example A program can be written without using any line numbers, as illustrated by
this short example. QQQ is used as a line label:
IMMEDIATE OFF
Ok
PRINT "LINE 1"
GOSUB QQQ
END
QQQ: PRINT "LINE 2"
RETURN
IMMEDIATE ON
Ok
RUN
LINE 1
LINE 2
Ok
