[one-users] Fwd: CONTEXT variables within each other

[Carlos Martín Sánchez]

Hi,

No, that can't be done. The way it is coded now, the template is not
"expanded" and then interpreted.
When the syntax finds ATT = VALUE, we look into VALUE to see if it starts
by $, but for $FILE="VALUE", value is interpreted and not expanded, even if
it starts by $.

I guess the feature request here would be to expand the VM template strings
starting by $, no matter if they are inside context or not.

Regards
