# Directives

DISABLE | Disable Use of Prefix Table Entry

## Format

DISABLE (prefix[,ERR=stmtref])
Where:

prefix | Numeric value of the prefix to disable. Numeric expression, integer.
stmtref | Program line number or statement label to which to transfer control.

## Description

Use the DISABLE directive to notify PxPlus that you do not want to use a given prefix table entry. This directive is used primarily in the conversion to or from old Business Basic languages where you could disable a specific disk drive.

To re-enable the prefix, use the ENABLE directive.

#### Note:
This directive is included in PxPlus for compatibility with other languages.

## See Also

## Example

prefix (1)"/disk1/data/"
prefix (2)"/disk2/data/"
disable (1)

This causes PxPlus to ignore prefix (1).
