In addition to the printer and font table variables, ICQCPC00 sets additional variables for a selected printer in the ISPF shared pool. The additional variables are prefixed with QCP. Some contain error information and are identified with the return codes in Table 1 and Table 1.

Other QCP variables store the contents of a printer's QAPLOC, QAPFORM, and QAPTYPE variables when the printer is selected. The application can then use these variables (QCPLOC, QCPFORM, QCPTYPE) to redisplay a former selection. Another variable, QCPID, contains a unique identifier for the print definition's row in the printer table.
