ABORT
Syntax
ABORT [expr]
Description
The UniBasic ABORT command terminates the program or subroutine in progress,
returning the user to the UniData system level. ABORT returns the user to the
UniData prompt, whether the aborted program was called by another program or
executed through a UniData menu or paragraph. ABORT can include an optional
string expr to display when the program aborts. The expression can contain variables,
functions, and/or arithmetic or string operators.
The UniBasic commands ABORT and PRINTERR return the system message whose
ID you specify in the command. You can also retrieve system messages using a
UniBasic program by opening the system message file and reading a message record
by ID.
Note: ENGLISH.MSG is the default system message file that is activated when you
install UniData. If you execute udtlang.config to select a language group, a different
system message file could be activated. To find out which language is installed on
your system, execute the ECL command SET.LANG CURRENT. For more
information, see UniData International.
The ABORT command in BASICTYPE P provides additional functions. ABORT
prints either a user-defined message specified by the string expr, or a UniData system
message identified by message-id:
ABORT [message-id]
ABORT [expr,...]
In the first form of the syntax, the message-id must be a variable that evaluates to a
key contained in the UniData message file. If no message exists, the number entered
in message-id is returned. In the second form of the above syntax, you can specify
more than one expr.
