Re: [U2] To DIM a passed Matrix or not ?
It IS necessary to DIM it in the called routine, not to establish its size (extent) but to establish the number of dimensions (1 or 2). In your example, DIM matrix(1) would have been sufficient. But DIM matrix(50,2) would cause a run-time error. - Original Message - From: Jacques G. [EMAIL PROTECTED] To: u2-users@listserver.u2ug.org Subject: Re: [U2] To DIM a passed Matrix or not ?

So my question is, are there MV flavors where it is neccessary to do so ? We use UniData with Pick flavor (under SB+). I tried this test program: SUBROUTINE MAT.TEST(MAT PARM) FOR I = 1 TO 100 PRINT PARM(I):, : IF NOT(MOD(I,10)) THEN PRINT NEXT I PRINT Done! RETURN When I tried to compile it, I got these errors: Compiling Unibasic: BP/MAT.TEST in mode 'p'. warning: PARM may be one dimension matrix. redefined variable PARM near line 3 matrix PARM undefined. compilation failed I had to add the DIM PARM(100) statement to get this to compile. Please note that the CALLING program determines the size of the array, not the subroutine. With the example above corrected, I tried the following program: DIM CHK(50) FOR I = 1 TO 50 CHK(I) = I * I NEXT I CALL MAT.TEST(MAT CHK) STOP When I ran the program, it bombed out when I=51, since CHK was only dimensioned to 50. Suggestion with this syntax: include the size of the array as a parameter. My corrected versions of these programs follow: DIM CHK(50) FOR I = 1 TO 50 CHK(I) = I * I NEXT I CALL MAT.TEST(MAT CHK,50) STOP SUBROUTINE MAT.TEST(MAT PARM, SIZE) DIM PARM(SIZE) FOR I = 1 TO SIZE PRINT PARM(I):, : IF NOT(MOD(I,10)) THEN PRINT NEXT I PRINT Done!

Re: [U2] To DIM a passed Matrix or not ?
In Universe, it isn't necessary to DIM a matrix that has been passed in a subroutine. Just to clarify what I meant here. The DIM or COM is still done but it is done in the calling program. It isn't neccessary to dim it in the SUBROUTINE in Universe. __ Do You Yahoo!? Tired of spam? Yahoo!

I've seen the following: SUBROUTINE FOO(MAT FOOBAR) DIM FOOBAR(100) [... some code] RETURN In Universe, it isn't necessary to DIM a matrix that has been passed in a subroutine. So my question is, are there MV flavors where it is neccessary to do so ? __ Do You Yahoo!? Tired of spam? Yahoo!
