PASCAL Data Type Mappings

To be compatible with PASCAL, the data types for the extracted entities as deﬁned in the

Dictionary must be mapped to PASCAL data types. The following shows how the

Dictionary data types are mapped to compatible PASCAL data types. Note that the

PASCAL type occupies the same storage length as the data types deﬁned in the Dictionary.

(The storage length is computed from the ELEMENT-LENGTH and ELEMENT-COUNT

entries for an entity in the Dictionary.)

Any ASCII character:

If the entity is deﬁned in the Dictionary as:

ELEMENT-TYPE = X

ELEMENT-LENGTH = N

The corresponding PASCAL data type will be generated:

CHAR (if N=1) or

PACKED ARRAY[1..N] OF CHAR (if N > 1)

For example, if an entity is deﬁned in the Dictionary as:

ELEMENT = ACCOUNT_NAME

ELEMENT-TYPE = X

ELEMENT-LENGTH = 20

The PASCAL code will be generated as:

ACCOUNT_NAME = PACKED ARRAY[1..20] OF CHAR

Uppercase alphanumeric string:

If the entity is deﬁned in the Dictionary as:

ELEMENT-TYPE = U

ELEMENT-LENGTH = N

The corresponding PASCAL data type will be generated:

' '..'Z' (if N = 1) or

PACKED ARRAY[1..N] OF ' '..'Z' (if N > 1)

Note that the PASCAL subrange ' '..'Z' restricts characters from being lowercase.

Numeric ASCII string:

If the entity is deﬁned in the Dictionary as:

ELEMENT-TYPE = 9 or 9+

ELEMENT-LENGTH = N

The corresponding PASCAL data type will be generated:

'0'..'9' (if N = 1) or
