END TRANSACTION is at the wrong level in the clip you sent us. Here is an
example from the manual.
BEGIN TRANSACTION
READU data1 FROM file1,rec1 ELSE ROLLBACK
READU data2 FROM file2,rec2, ELSE ROLLBACK
WRITE new.data1 ON file1,rec1 ELSE ROLLBACK
WRITE new.data2 ON file2,rec2 ELSE
Correction to the code listing... All RETURNS should be CONTINUEs.
Appologies,

Logically there *is* an END TRANSACTION at two places. One at the
bottom of the loop..
COMMIT
END TRANSACTION
And the other at the top of the loop...

This being the case it would seem to me that the compiler cannot deal
with a
The help for END TRANSACTION says:
Use the END TRANSACTION statement to specify where processing is to
continue after a transaction ends.
This implies to me that there must be exactly one end transaction for
each begin transaction. It also implies that if you do a rollback,

A transaction may only have a single BEGIN and END statement. You are
basically creating a logic block that contains the code that makes up the

First, you could move the begin transaction above the LOOP and the End
transaction after the REPEAT.
Perry,
You probably won't be able to have multiple END TRANSACTION statements.
One BEGIN TRANSACTION where you have it, and one END TRANSACTION at the bottom
of the LOOP structure, should suffice.
Then just put a ROLLBACK and CONTINUE within each IF-, READ-, and
Hi,
I am trying to run a unibasic program (external subroutine) that takes
two arguments.
I don't know how do I pass it the arguments if I run it directly from
shel prompt instead of calling it from another program.
I have gone through the manual, but can't find anything. Pls help.
Thanks
You'll have to write a wrapper that translates the two command line
parameters into subroutine arguments.

Hi, Savita. I presume you mean running the program from TCL (:), the U2
command prompt.
In UniData there are two built-in variables, synonyms actually, named
@SENTENCE and @COMMAND. These contain the raw command line used to
invoke your subroutine.
I usually TRIM this (to eliminate multiple

[snip] Gordon, I would think that you could address it with file

Can PRC work around that one?
