Given what you have included, the best that i can tell you is that it tests some variable (1 byte in length) for some bit or set of bits (depending on how SDLET is defined). It is usually followed by a branch on condition or a branch relative on condition. You have not said how I2REC, ISTAT, IREC, and SDELT are defined; nor what follows.
