Tricia,
The following is from the R:Base Syntax HTML documents. This should explain
those weird PROMPTS.

R:BASE Prompts
We are all familiar with, and have often times come to love, the venerable
R> Prompt. However, there are other prompts that you will run across from
time to time when using R:BASE. This document attempts to list them and
discuss how to exit the Prompt safely.
PromptDescriptionExit Method
R>This is the standard Command Entry prompt. (Exiting this will exit
R:BASE)EXIT or QUIT
B>Indicates that you have entered a BREAK command but have not reached the
end of the looping structure (such as an ENDSW).In most cases ENDSW. The
[Esc] key may work.
I>This prompt indicates that you are currently within an IF or ELSE body
block for conditions that are not met.ENDIF
L>This indicates that you are in a LOAD table status.END
S>This indicates that you are inside a SWITCH or CASE command block for the
non-matching CASEs for a SWITCH but that you have not yet matched a case.
Once you have matched a case this is replaced by the B> Prompt. ENDSW
W>This indicates that you are inside of a WHILE loop command block.ENDWH
Examples
The following examples must be typed at the R> Prompt.
The following example shows the I> Prompt.
R> IF 'A' = 'B' THEN
I> WRITE 'TRUE' *(The I> Prompt indicates this is not
being processed and we are waiting
for a control structure such as an
ELSE or ENDIF)
I> ELSE
R> WRITE 'FALSE' *(The R> Prompt indicates commands
are being processed. In this case,
because A does not equal B. What follows
on the next line is the output from
the WRITE command.
FALSE
R> ENDIF
The following example illustrates the S> and B> Prompts.
R> SET VAR vX INT = 1
R> SWITCH (.vX)
S> CASE 0 *(As with the I> Prompt the S>
Prompt indicates a CASE has not
matched the value of the vX
variable.)
S> WRITE 'I am zero'
S> BREAK
S> CASE 1
R> WRITE 'I am one' *(The prompt changes to "R>" because
this is the "active" case. What
follows on the next line is the
output from the WRITE command.)
I am one
R> BREAK
B> CASE 2 *(Here is the "B>" where the SWITCH is
looking for the "ENDSW" command. This
happens because the MATCH has been
found and all further commands
should be ignored.)
B> WRITE 'I am two'
B> BREAK
B> ENDSW
R> *(Here we have exited the SWITCH structure.)
The following example illustrates the W> Prompt. Once the ENDWH command is
entered many lines of text will be written to the screen. These lines will
terminate after one minute.
R> SET VAR vLater TIME = (ADDMIN(.#TIME,1))
R> WHILE #TIME < .vLater THEN
W> WRITE 'Not Yet: ' .#TIME
W> ENDWH
The following commands will illustrate the L> Prompt. They also create a new
database named TestLPrm which can be deleted.
R> CREATE SCHEMA AUTH TestLPrm
R> CREATE TABLE TestLPrm (TestCol INT)
R> LOAD TestLPrm
L> 1 *(The L> Prompt indicates that R:BASE
is waiting for data to be entered.
L> 2
L> 3
L> END
R>

I did a simple command at the R> and I got a B>.
Does anyone know why that happend and what I need to do to get back to the
R> ? Tricia
