CVTIIV

Pass an integer value to a field

The CVTIIV routine was deprecated in Synergy/DE version 9; we recommend you use an integer assignment instead, as shown in the note in the Discussion.

xcall CVTIIV(value, field)

Arguments

value

Passed directly or using one of the following functions: (n)

^VAL = Pass the integer by value.

^REF = Pass the integer by reference.

^XTRNL = Pass the integer by external reference. (OpenVMS only)

field

The variable that will be loaded with the binary value. (n)

Discussion

We recommend that you replace the deprecated CVTIIV routine with an integer assignment. For example,

xcall cvtiiv(^ref(prcnmlen),retlen) would become

retlen = ^addr(prcnmlen)

xcall cvtiiv(^val(numeric field), retlen) would become

retlen = numeric field

xcall cvtiiv(^xtrnl(SOME LITERAL), retlen) would become

retlen = ^xtrnl(SOME LITERAL)

See Moving integer data to a decimal/packed destination for more information about assigning integer values.

The CVTIIV subroutine converts an integer value to a specified field with no data type conversion. The integer must be passed by value, reference, or external reference.

The CVTIIV subroutine supports only three integer sizes:

1	Byte size
2	Word size
4	Longword size

Designating a size other than 1, 2, or 4 generates an “Argument specified with wrong size” error ($ERR_ARGSIZ).

You can use this routine to store the address of a field in a variable by using the ^REF function as the first argument. You can also use CVTIIV to store an externally defined constant or address by using the ^XTRNL function.

Examples

xcall cvtiiv(^ref(variable), byte_val)
