Re: Initialize a string to a named constant

No you wouldn't need to do the for loop.

MyArray(*) = efdFldDelim;

The * says to populate all array elements with the same value.

Then I still have to use the For loop for filling.

Had a brainstorm and tried this:

Subst(DelimFill:1:%Len(DelimFill)) = efdFldDelim;

which only put in a single semicolon. Then I tried:

%Subst(DelimFill:*All) = efdFldDelim;

which passed the syntax check in RDi, but not the "compiler" check. :)

If you still have it defined as an array, you could

MyArray(*) = efdFldDelim;

Or initialize all array elements to that value.

A couple of weeks ago, I asked about concatenating an entire array to a

Jeff said one thing that puzzles me. He said it's always filled with

something

like that? Just do this:

string = *all';';

now the string is filled with all semicolons. isn't that a lot

easier?

to which I responded:

Yes it is, and I like it.

This is for a new application where I need to create a number of files

that

will be FTP'ed offsite. Each file has a variable number of fields

with a

semicolon as the field separator.

Each file has, as the last record, a BATCHCONTROL record with file

totals,

I need to put a variable number of semicolons at the end of this batch
control record so this record has the same number of fields as the

detail

records in the file. I want to use the exact same logic in each

program

that builds a file and, for some reason, got fixated on using an array

and

just setting the DIM of the array to the number of semicolons I need.

But

it's even simpler to just define a field in the program to the size I

need

initialized to semicolons and use it. Duh.

</quote>


I want to take it a step further. Instead of doing this:

dcl-s DelimFill Char(37) Inz(*All';');

to initialize the variable with all semicolons, I want to initialize it

all

with a named constant I have already defined:

dcl-c efdFldDelim ';';

so I tried this:

dcl-s DelimFill Char(37) Inz(efdFldDelim);

But, as I expected, it only puts in a single semicolon. I tried this:

dcl-s DelimFill Char(37) Inz(*ALLefdFldDelim);

which throws a syntax error, as I expected. I'm guessing it's not
possible?

An alternative would be to initialize as blanks, then assign all

semicolons

in one fell swoop, but this also throws a syntax error:

DelimFill = *ALLefdFldDelim;

and I can't put quotes around efdFldDelim because then DelimFill would

have

"efdFldDelim" as it's contents.

Again, this not possible either?

Don't see examples in the manuals doing either of these. V7R1 up to

date

on PTFs.

Thanks.
