Vector test zoned instruction for validity testing

A computer system for facilitating processing within a computing environment, the computer system comprising:

• at least one computing device;
• a set of one or more computer readable storage media;
• and
• program instructions, collectively stored in the set of one or more computer readable storage media, for causing the at least one computing device to perform the following computer operations including:
• executing an instruction to perform validity testing of a source value, the executing the instruction including:
• obtaining the source value using at least one field of the instruction;
• performing validity testing of at least a portion of the source value based on one or more test controls obtained using a field of the instruction, wherein the performing the validity testing determines whether a format of the at least the portion of the source value adheres to a data format variation specified by, at least, the one or more test controls, and wherein the performing the validity testing provides a result;
• and
• providing the result for use in further processing.

A computer-implemented method of facilitating processing within a computing environment, the computer-implemented method comprising:

• executing an instruction to perform validity testing of a source value, the executing the instruction including:
• obtaining the source value using at least one field of the instruction;
• performing validity testing of at least a portion of the source value based on one or more test controls obtained using a field of the instruction, wherein the performing the validity testing determines whether a format of the at least the portion of the source value adheres to a data format variation specified by, at least, the one or more test controls, and wherein the performing the validity testing provides a result;
• and
• providing the result for use in further processing.

A computer program product for facilitating processing within a computing environment, the computer program product comprising:

• a set of one or more computer readable storage media;
• and
• program instructions, collectively stored in the set of one or more computer readable storage media, for causing at least one computing device to perform computer operations including:
• executing an instruction to perform validity testing of a source value, the executing the instruction including:
• performing validity testing of at least a portion of the source value based on a plurality of test controls obtained using a field of the instruction, the performing the validity testing comprising:
• determining that a format of the at least the portion of the source value adheres to a data format variation specified by, at least, one or more test controls of the plurality of test controls;
• and
• ascertaining, using at least one test control of the plurality of test controls, that one or more digits and a sign code of the at least the portion of the source value are valid;
• and
• providing a result of the validity testing for use in further processing.

A computer program product for facilitating processing within a computing environment, the computer program product comprising:

• a set of one or more computer readable storage media;
• and
• program instructions, collectively stored in the set of one or more computer readable storage media, for causing at least one computing device to perform computer operations including:
• executing an instruction to perform validity testing of a decimal number in a zoned format, the executing the instruction including:
• performing validity testing of the decimal number based on a plurality of test controls obtained using a field of the instruction, the performing the validity testing comprising:
• determining that a format of the decimal number adheres to a zoned format variation specified by, at least, one or more test controls of the plurality of test controls;
• and
• ascertaining, using at least one test control of the plurality of test controls, that one or more digits and a sign code of the decimal number are valid;
• and
• providing a result of the validity testing in a condition code of the instruction for use in further processing.
