Multi line SET statement

[Ulf Pettersson]

I cant find a practical way to extend a muti-variable assignment across multiple
code line.

This is needed when there are many values to assign (that cant fit on one line) or
when assignment need to be done in a loop or in in separate statements.

A few possible approaches are:

#set myMultiVariable = "Value1", "Value2", "Value3", "Value4"

#set myMultiVariable = ?@myMultiVariable?, "Value5", "Value6", "Value7", "Value8"

or

#set myMultiVariable = "Value1", "Value2", "Value3", "Value4"

#set myMultiVariable = myMultiVariable + "Value5", "Value6", "Value7", "Value8"

or

#set myMultiVariable = "Value1", "Value2", "Value3", "Value4",

#set myMultiVariable += "Value5", "Value6", "Value7", "Value8"

If I recall correct, I used the first of the above when using XVCL.

Dear Ulf,

I think it wouldn't be a problem to add the ability to continue a #set command in the next line, which would mean having a #set command in multiple lines.

For extension of a variable:
I would also suggest the first option given. You recall correctly, I tried these things in XVCL.

So

#set myMultiVariable = "Value1", "Value2", "Value3", "Value4"
#set myMultiVariable = ?@myMultiVariable?, "Value5", "Value6", "Value7", "Value8"

Will result a multi-variable having values: "Value1", "Value2", "Value3", "Value4", "Value5", "Value6", "Value7", "Value8"

However we have to forbid extension of a variable, which is a control variable of any currently processed loop, since that would be unsafe and could lead to errors.
