Following a slash (/), the qualifiers below can appear in any SHOW statement.

indicates that you want information only on relevant options of the RESET statement. The following will not be displayed if / RELEVANT is specified:

• information on noncurrent data sets

• the options that control the reasons why stage 1 optimization should be halted and the options that control the simplex algorithm during stage 1 optimization, if the unconstrained optimum has been reached or constrained optimization has been performed

• if P1SCAN=BEST or P1SCAN=FIRST, the P1NPARTIAL= option is irrelevant

• if PRICETYPE1=BLAND or PRICETYPE1=NOQ, the options QSIZE1=, Q1FILLSCAN=, REFRESHQ1=, and REDUCEQSIZE1= are irrelevant

• if Q1FILLSCAN=BEST or Q1FILLSCAN=FIRST, the Q1FILLNPARTIAL= option is irrelevant

• the options that control the reasons stage 2 optimization should be halted, the options that control the simplex algorithm during stage 2 optimization, if the constrained optimum has been reached

• if P2SCAN=BEST or P2SCAN=FIRST, the P2NPARTIAL= option is irrelevant

• if PRICETYPE2=BLAND or PRICETYPE2=NOQ, the options QSIZE2=, Q2FILLSCAN=, REFRESHQ2=, and REDUCEQSIZE2= are irrelevant

• if Q2FILLSCAN=BEST or Q2FILLSCAN=FIRST, the Q2FILLNPARTIAL= option is irrelevant

indicates that you want to examine only the options that affect the optimization that is performed if a RUN statement is executed next. Before any optimization has been done, only stage 2 options are displayed if the problem has side constraints and the SCRATCH option is used, or if the CONOPT statement is specified. Otherwise, stage 1 options are displayed. If still optimizing neglecting constraints, only stage 1 options will be displayed. If the unconstrained optimum has been reached and optimization that considers constraints has not been performed, stage 1 options are displayed. If the problem has constraints, stage 2 options are displayed. If any optimization that considers constraints has been performed, only stage 2 options are displayed.
