TALALLOCATE Command
The TALALLOCATE command allocates memory in pTAL or TAL for single-field
definitions. NOTALALLOCATE enables DDL to generate pTAL or TAL source code for
single-field definitions without memory allocation. When NOTALALLOCATE is in effect,
DDL translates single-field definitions into pTAL or TAL DEFINEs or STRUCT
templates.
TALALLOCATE
allocates memory for single-field definitions when the TAL command is in effect.
TALALLOCATE is the default.
NOTALALLOCATE
suppresses memory allocation when the TAL command is in effect, causing DDL to
translate single-field definitions into pTAL or TAL DEFINEs or STRUCT templates.
TALALLOCATE Command Examples
The following examples show pTAL or TAL output for the same DDL definitions when
TALALLOCATE is in effect and when NOTALALLOCATE is in effect.
DDL Type: pTAL or TAL Type:

END.
