A procedure may have parameter by reference.

In C/SIDE a text-parameter would inherit the length-property from the caller.

Example:

1 Declaring global var myGlobalText[33]

2 Declaring “myProcedure(VAR prmTextVariable[10])” (or whatever length, is any)

3 Calling myProcedure(myGlobalText)

In C/SIDE prmTextVariable would hold a maxlength at 33 bytes.

In AL it holds maxlength at 10 bytes (or whatever declared; if undeclared, then max is 250).

The C/SIDE-way is definitely preferable.

Reason is that in some cases a a variable should not exceed a specific lenght in e.g. various reportings.

And using a procedure for a (repeating) task like this is absolutely the right path to go.

But in AL it is useless.
