Line Label (procedure)
Commands in a procedure file may start with a line label. The label must begin with a colon (:) and may be up to 800 alphabetic, numeric or underscore characters in length (spaces are not allowed). Procedure labels do not have to be followed by a command. Both the following procedure lines are acceptable:
:NEXTRUN :START PROC MENU
When typed in without a line number and during READY mode, most statements can be executed immediately. Statements without line numbers or labels may also be included in procedure files. Statements used in both these ways may include a comment at the end of the statement.
The comment must be separated from the rest of the statement by at least one space and an exclamation point, or it may be set off with the use of the REM statement.
The following example shows the OPEN (Ope) statement being used in immediate mode:
