{{Built-in|I-Beam|⌶}} is a [[primitive operator|primitive]] [[monadic operator]] that takes a numeric code as it's [[operand]] and [[derived function|derives]] an [[ambivalent]] function which provides a range of ad-hoc operations. This range covers non-[[primitive function]]s - for example: experimental features, interpreter-level control, access to the environment, and information about APL itself. | {{Built-in|I-Beam|⌶}} is a [[primitive operator|primitive]] [[monadic operator]] that takes a numeric code as it's [[operand]] and [[derived function|derives]] an [[ambivalent]] function which provides a range of ad-hoc operations.

I-Beam was introduced in [[APL\360]] by implementers to execute [[wikipedia:IBM System/360|System/360]] instructions from program control. The convenience of this lead to I-Beam becoming directly available to use by anyone.<ref>[https://dl.acm.org/doi/pdf/10.1145/585923.585925 The Design of APL]</ref> | |||
