Comments

Protected and unprotected programs, groups, and appvars have variable length names, while matrices, strings, pictures, GDBs, etc. have fixed names.

Some lists have fixed names while some do not, and this BCALL handles this by checking the first character of the name. Fixed lists have the byte 24h, 3Ah, or 72h (the tAns token).

This BCALL is used somewhere within DelVar.
