Copying between basic ABL data types and MEMPTR
The following table lists the basic ABL data types and how you can copy them in and out of a MEMPTR variable.
Table 48. 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.
INTEGER2
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.
LOGICAL3
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.
