Hello, this is probably an easy one for you but I did not find any hint in the doc so far.

When defining a simple array, I can initialize it at the same time:

DEFINE myarray1 ARRAY [4] OF INTEGER = [ 1, 2, 3, 4 ]

But when defining a two-dimensional array like this:

DEFINE myarray2 ARRAY [2,4] OF INTEGER

How is the syntax then? I tried different variants but was not successful so far.

Thank you very much in advance,
Hajo

Hi!

sf@toro:/tmp$ cat a.4gl
IMPORT util
 
DEFINE arr ARRAY[5,3] OF INTEGER = [
 [1,2,3],
 [1,2,3],
 [1,2,3],
 [1,2,3],
 [1,2,3]
]
 
MAIN
    DISPLAY util.JSON.stringify(arr)
END MAIN
sf@toro:/tmp$ fglcomp -M a.4gl && fglrun a.42m
[[1,2,3],[1,2,3],[1,2,3],[1,2,3],[1,2,3]]
 

Hello Sebastien, thank you for your fast reply.

This way of initialization was actually among the ones I tried, but I am always getting this:

Compiling 'jobs/testArr.4gl'
testArr.4gl:4:1:4:1:error:(-6609) A grammatical error has been found at '[' expecting: CHAR_CONST INT_CONST DEC_CONST IDENT DATETIME FALSE INTERVAL MDY NOTFOUND NULL TRUE '+' '-' '(' '%'.
::error:(GS-1072) The command 'fglcomp --build-rdd -M /opt/gstshare/watmes_khj/jobs/testArr.4gl' failed with exit code 1.
*** Failure [15:01:28] ***

I am using exactly your code:

IMPORT util
 
DEFINE arr ARRAY[5,3] OF INTEGER = [
[1,2,3],
[1,2,3],
[1,2,3],
[1,2,3],
[1,2,3]
]
 
MAIN
   DISPLAY util.JSON.stringify(arr)
END MAIN

Was there maybe a bugfix which I am missing in the compiler?
I am  using Studio 4.00.03 with the matching version on the Linux host.

Thank you very much,
Hajo
