Size
A size is an integer that specifies the number of lines to be allowed in a workfile. The minimum size is 200 lines, and the the maximum is either 65,535 (original-format workfiles) or 99,999,999 (Jumbo and Wide-Jumbo workfiles). The default size is 3,200 lines, but can be changed with Set Work Size. This term occurs in the New, Text and Set Work Size commands:
/new abc(1000) {build “abc” with room for 1,000 lines}
/text q(5000)=s {build “q” for 5,000 lines, copy S in}
/s work size 600 {set default size for NEW workfiles}
