Dynamic array versus matrix

    • Within a jBase-Basic program, a data array can be represented as a Dynamic Array:

dynamic array

– Used with array_name<datax>

  • or alternatively as a Matrix:

dimensioned array

– A typical example of matrice is R.NEW
– Also named «dimensioned array»
– Used with: array_name(datax)

To be noticed:

– When writing in a table, always do it with a dynamic array.

– When passing an array as a parameter (argument) with a CALL <subroutine> , always do it with a dynamic array.

Alternatively, if the parameter of the CALL <subroutine> is a matrix, indicate it using a MAT before the parameter name.

Example if param2 is a matrix:    CALL SUBROUTINE(param1, MAT param2).

  • Functions used to convert a MATRIX to a DYNAMIC array:

Dimensioned to Dynamic

MATWRITE array TO file.variable, record ID

MATBUILD dynamic.array FROM array (,start (,end)) (USING delimiter)

 

  • Functions used to convert a DYNAMIC to a MATRIX array:

MATPARSE array FROM dynamic.array (,delimiter)

MATREAD array FROM file.variable, record ID
