RE: Can't See the Difference

Carel,

Thanks, but #Limit is a global variable that is only set after the Load All
subfile is, well, loaded. It is set to the value of RRNA, which is the
subfile's relative record number.

Plus, I can see the code running the FOR loop, just not getting a successful
hit on the CHAIN. STRDBG does show that 'x' has the proper value on both
the FOR line and the CHAIN line.

Jerry,

Do you reset #limit to zero before strting the loop in the subroutine.
In the subprocedure it is automatically reset as a local variable.

I am thoroughly bamboozled by this one.

I have code in two places in my program that loop through a subfile.
The

code is essentially the same. The first set is in a subroutine and the

second set is in a subprocedure. The subprocedure set works; the

subroutine set doesn't. It's the latter that's got me puzzled (obviously).

I have stared at this all morning and can't see any difference between
the two sets of code, but I've only got one eye and it's aged and often
blurry after staring at a terminal most of the day. Maybe someone else
can point

out what is probably an obvious flaw that I can't see.

Subroutine code (not working):

IF #limit > *Zeros;

FOR x = 1 to #limit;

CHAIN x DTU020A;

IF %found();

(some code)

Subprocedure code (working):

IF #Limit > *Zeros;

FOR x = 1 to #Limit;

CHAIN x DTU020A;

IF %found();

(different code)

In the interest of full disclosure: the definitions of the variables are:

D #Limit S Like(rrna)
D X S Like(rrna)

And rrna is the relative record number of the subfile record (DTU020A).
The >debug of the subroutine code on the CHAIN 'x' has a value of '1'.

After the IF %found(), the subroutine bypasses all of the "some code"
stuff. The FOR

loop runs for as many records as there are in the subfile; it's the
CHAIN

in the subroutine that doesn't find the subfile record.
