Synopsis

Unofficial Name: IsFixedName

BCALL Address: 4363

This BCALL determines whether a variable's name has a fixed size or is of varying length.

Inputs

  • HL points to VAT entry's type byte

Outputs

  • NZ set if fixed name

Destroys

  • A

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.
