#TACLVERSION Built-In Function

Use #TACLVERSION to determine which RVU of TACL you are using.

Result

With the REVISION option, #TACLVERSION returns only the RVU-level portion of the

version identifier, followed by a revision level identifier, in the form:

Xnn nnnn

where Xnn is the RVU identifier (C20, for example) and nnnn is a four-digit number

identifying the revision level within that RVU. That number is incremented whenever an

interim product modification is made to the RVU.

This form of revision number can be collated. For example, if a macro operation

depends on a feature released in a particular RVU of TACL, such as C20 0011, the

macro can test to see if the current RVU is equal to or greater than that RVU:

[#IF "[#TACLVERSION/REVISION/]" '>=' "C20 0011" |THEN| ...

Without the REVISION option, #TACLVERSION returns the current TACL RVU

identifier.
