Calculation Specifications

The operation code READ is valid for a program-described WORKSTN file that is defined as a combined, full-procedural file. See Table 1. The file name must be specified in factor 2 for this operation. A format must exist at the device before any input operations can take place. This requirement can be satisfied on a display device by conditioning an output record with 1P or by writing the first format to the device in another program (for example, in the CL program). The EXFMT operation is not valid for a program-described WORKSTN file. You can also use the EXCEPT operation to write to a WORKSTN file.
