PowerD.html - TDEF definition

Description:
TDEF keywords allows You to define Your own types, like with C's typedef. It is a bit more limited, than it's C's equivalent, but can do the same job.

Syntax:

  TDEF   <name>           // the <name> is the VOID type
  TDEF   <name>:<type>    // the <name> is the <type> type
  TDEFL  <name>           // the <name> is the LONG type
  TDEFUL <name>           // the <name> is the ULONG type
  TDEFB  <name>           // the <name> is the BYTE type
  TDEFUB <name>           // the <name> is the UBYTE type
  TDEFW  <name>           // the <name> is the WORD type
  TDEFUW <name>           // the <name> is the UWORD type
  TDEFF  <name>           // the <name> is the FLOAT type
  TDEFD  <name>           // the <name> is the DOUBLE type

Example:
If You often use the 'PTR TO RastPort' type, You can define:
```
  TDEF RP:PTR TO RastPort
```
and then You can simply replace all the 'PTR TO RastPort' types by short 'RP'.
