The following table lists the basic ABL data types and how you can copy them in and out of a MEMPTR variable.

Table 1. Copying between basic ABL data types and MEMPTR
Data type Copying to/from MEMPTR
DATE To copy into a MEMPTR:
  • Use INTEGER(date-expression) to obtain an integer value
  • Use the PUT-LONG statement to copy integer value to MEMPTR
To copy from a MEMPTR:
  • Use the GET-LONG function to return the integer value
  • Use the DATE(integer-expression) function to return the date
DECIMAL1 To copy into a MEMPTR, use the PUT-DOUBLE or PUT-FLOAT statement.

To copy from a MEMPTR, use the GET-DOUBLE or GET-FLOAT function.
INTEGER1 To copy into a MEMPTR, use the PUT-LONG, PUT-SHORT, PUT-UNSIGNED-SHORT, or PUT-BYTE statements.

To copy from a MEMPTR, use the GET-LONG, GET-SHORT, GET-UNSIGNED-SHORT, or GET-BYTE functions.
LOGICAL1 To copy into a MEMPTR, use the PUT-LONG, PUT-SHORT, PUT-UNSIGNED-SHORT, or PUT-BYTE statements.

To copy from a MEMPTR, use the GET-LONG, GET-SHORT, GET-UNSIGNED-SHORT, or GET-BYTE functions.
RAW To copy into a MEMPTR, assign the RAW value directly using an assignment statement or use the PUT-RAW statement.

To copy from a MEMPTR, assign the MEMPTR value directly using an assignment statement or use the GET-RAW function.
1 The choice of exact statement or function to use depends on the data type used by the shared library routine or the socket application with your application is communicating.
