This chapter describes the M Intrinsic Special Variables implemented in GT.M. All entries starting with the letter Z are GT.M additions to the ANSI standard Intrinsic Special Variables. None of the Intrinsic Special Variables are case sensitive.

M Intrinsic Special Variables start with a single dollar sign ($). GT.M provides such variables for program examination. In some cases, the Intrinsic Special Variables may be set to modify the corresponding part of the environment.
