Trace control can also be set by
statements
within a function. These
statements
initiate tracing when a variable contains a certain value. For example:
I:
:1,]
[2]
[3]
[4]
[~:'i]
VBTEVEf:I]J'\I
V
STEVE
I

Note: The following instruction will establish trace control for
the
first
statement
of
each user-defined function in
the
active workspace:
J.
"'l
t,
I 0 ' , '
(.)
· , T · ) ,
IJ.
' } ( (
(I]NL
:3)"
'~
..
' ) } ,
:l
' ) J '
This instruction can be used
to
find
out
what
functions are called by
another
function.
The following user-defined function named TRACE will establish a trace vector
for each
statement
in a specified user-defined function:
VTRACE[DJV
'iJ
TRACE
NANE
[1]
!'T6',NAME,
'~\ltpOCR'"
