1. A computer system comprising: one or more computer processors; one or more computer readable storage media; program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising: program instructions to provide one or more system control blocks identifying software modules that have been loaded into memory without directed loads, and a directed load table identifying software modules that have been loaded into memory via directed loads, wherein the directed load table includes a wrapping feature that replaces older entries when space for newer entries is required; program instructions to receive a request for a directed load of a software module into memory, wherein the request for the directed load includes an address for storing the software module; program instructions to store the software module at the address according to the received request; program instructions to add a name and an address range of the stored software module to the directed load table; program instructions to receive a first query that includes an input module name; program instructions to, responsive to determining that the input module name of the received first query is not stored in the one or more system control blocks, search the directed load table for the input module name of the received first query; program instructions to, responsive to determining that the input module name of the received first query is stored in the directed load table, return an address range associated with a software module matching the input module name in the directed load table; program instructions to receive a second query that includes an input address range; program instructions to, responsive to determining that the input address range of the received second query is not stored in the one or more system control blocks, search the directed load table for the input address range of the received second query; program instructions to, responsive to determining that the input address range of the received second query is stored in the directed load table, return a name associated with a software module matching the input address range in the directed load table; program instructions to receive a third query that includes an input module name or an input address range; program instructions to, responsive to determining that the input module name or input address range of the received third query is not stored in the one or more system control blocks, search the directed load table for the input module name or input address range of the received second query; and program instructions to, responsive to determining that the input module name or input address range of the received third query is not stored in the directed load table, return an indication that no match has been found.
