#INTERACTIVE Built-In Function

Use #INTERACTIVE to determine whether your TACL is interactive. TACL is

considered to be interactive if its IN and OUT files are the same.

Result

If you include the CURRENT option, #INTERACTIVE returns -1 if the current IN file is

the same as the current OUT file (the contents of #IN are the same as the contents of

#OUT); otherwise, it returns 0.

If you omit the CURRENT option, #INTERACTIVE returns -1 if the primary IN file is the

same as the primary OUT file; otherwise, it returns 0.

The primary IN and OUT files are those in effect when TACL first starts (specified by

the IN and OUT run options in the RUN command that initiates the TACL process).

The current IN and OUT files may be different from those, if #SET #IN or #SET #OUT

have been executed.

Consideration

TACL automatically determines whether it is interactive when it first starts to run.
