17 /* Short names for variables.
19 PSPP allows variable names to be up to 64 bytes long, but the
20 system and portable file formats require that each variable
21 have a unique name no more than 8 bytes long, called its
22 "short name". Furthermore, each "very long" string variable
23 that is more than 255 bytes long has to be divided into
24 multiple long string variables within that limit, and each of
25 these segments must also have its own unique short name.
27 The function in this module generates short names for
28 variables with long names or that have very long string
