The runtime behaviour of a DataBasic program or subroutine is determined by a combination of two factors:
These runtime settings are listed below. Click on the setting you require for details.
To find out in which compatibility modes a particular option is set, use the Basic Control Maintenance (BCM) utility. On versions of Reality earlier than that stated in Introduced on, the option is not set.
If set, causes user exit U50BB to behave as appropriate for the selected MultiValue compatibility mode (if any) set with the $OPTIONS statement.
Operation: See User Exit Conversions.
Introduced on: Reality V14.2.
Enable vendor mapping of @(-n).
Operation: See @ function (MultiValue).
Introduced on: Reality V9.1.
Special handling of ACCESS.
Documentation not yet available.
Allow commas to be used as line continuation characters.
Note: If line continuation is required immediately following a comma that is required by the syntax, two commas or a comma and an ellipsis must be used.
Operation: As on D3, mvEnterprise and UniVerse.
Introduced on: Reality V14.2.
Limit the values returned in the SETTING/RETURNING clause of an EXECUTE statement to error numbers only.
Operation: The EXECUTE statement operates as on D3.
Introduced on: Reality V14.2.
Allow DCOUNT to use a substring.
Operation: The DCOUNT function operates as on mvEnterprise.
Introduced on: Reality V14.0.
Allow IN to echo printable characters.
Operation: The IN statement operates as on mvEnterprise.
Introduced on: Reality V14.0.
Allow extended format of MATCH.
Documentation not yet available.
Position/Limit key literals are in external format.
Operation: Determines how indexes that were created from dictionary definitions that include output conversions are handled by the DataBasic POSITION and LIMIT.INDEX statements. Clear for compatibility with earlier versions of Reality.
Introduced on: Reality V14.1.
Special handling of descale value in Format mask.
Operation: Controls the outcome of combining precision and scaling in a format string.
Introduced on: Reality V9.1.
PERFORM to work with a GLOBAL active list.
Operation: Determines whether the default SELECT list is local or global.
Introduced on: Reality V9.1.
Adjust DataBasic INPUT timeouts.
Allow Multiple Pattern Separators.
Operation: Pattern matching functions as on mvEnterprise.
Introduced on: Reality V14.0.
Skip PRECISION -> SCALE if not specified in ML or MR format.
Documentation not yet available.
mvBase or mvEnterprise OPENSEQ mode.
Documentation not yet available.
Allow OPEN and READ statements to compile without THEN/ELSE.
Operation: Determines whether THEN/ELSE clauses are required in OPEN, READ, READU, READV, READVU, MATREAD and MATREADU statements.
When set, if the statement fails, the result (returned in the appropriate parameter) is null.
Introduced on: Reality V14.1.
Exclude new DataBasic intrinsic functions when compiling.
Operation: Intrinsic functions that are new in the current version of the DataBasic compiler are not compiled; this avoids problems caused by existing arrays having the same names as these functions.
Note that this is only a temporary solution, since in the next version of the compiler the functions will no longer be new. The recommended solution is to rename the arrays concerned.
Introduced on: Reality V14.2.
Set if no upscaling of precision in FORMAT.
Operation: Determines the outcome of combining precision and scaling in a format string.
Introduced on: Reality V14.0.
Format to operate on 1st field only.
Documentation not yet available.
Special handling of ONGOTO and ONGOSUB.
If set REM()/MOD() = remainder else modulo.
Operation: Determines how the MOD and REM functions behave when used with negative numbers.
Introduced on: Reality V14.0.
Return one instead of zero at end of string.
Documentation not yet available.
Use mvE right alignment mechanism.
Operation: Controls the behaviour of the LOCATE statement.
Introduced on: Reality V14.0.
Convert SELECT to a SELECTE if list pending.
Documentation not yet available.
Map SYSTEM via vendor map.
Documentation not yet available.
Allow zero to be returned in SUM.
Operation: Determines the SUM function's return value when passed an empty dynamic array.
Introduced on: Reality V14.0.
Treat strings containing only arithmetic unary operators and decimal points as numeric.
Operation: Treat the strings "+", "-", ".", "+." and "-." as numeric.
Introduced on: Reality V14.2.
Map SYSTEM through Reality map.
Documentation not yet available.
Convert TRIM 'M' to TRIM 'R'.
Operation: Controls the behaviour of the DataBasic TRIM function with type equals "R".
Introduced on: Reality V14.1.
AND, OR to only return 1 or 0 as result.
Operation: Controls how arithmetic expressions are evaluated when used in logical expressions, and how complex logical expressions are evaluated.
Introduced on: Reality V14.1.
Allow Non-null Non-numeric String to be seen as TRUE.
Operation: Determines whether non-numeric strings can be used in logical expressions.
Introduced on: Reality V14.0.
Set if COUNT/DCOUNT matches characters only.
Operation: Controls whether the COUNT, COUNTS, DCOUNT and INDEX functions match only non-overlapping strings.
Introduced on: Reality V14.2.
Allow USER exits.
