This function replaces all variable placeholders (several possible) like @MY_VAR@ in string a with the value of the variable(s) if the variable is defined in the profile (otherwise not).

If the variable value itself again contains a variable placeholder of the form @VAR_NAME2@, the function must be called again with the return value of the first call to guarantee the resolution of the variable placeholder contained in the value. If the resolution is already done in the first call, it would be random (cannot be guaranteed).

Parameters

Parameter	Description
a	Text containing the variable placeholders(s).
b	(optional) true to resolve date and time placeholders like <yyyy> or <HH> as well. Default: false.
