Problem:

I have lots of similar datasets that I need to merge into one large dataset. How can I do this in Mainframe Express?

Resolution:

Since your datasets have the same attributes, you can use JCL similar to this:
 
//MFIADS1M JOB (MFIADS),'MFIADS',CLASS=A,MSGCLASS=D,
//       REGION=8M,NOTIFY=MFIADS TYPRUN=SCAN
//*----------------------------------------------------
//DEL01    EXEC PGM=IEFBR14
//SYSUT2   DD DSN=LORINCE.FIFTY.A0811,DISP=(MOD,DELETE),
//            SPACE=(CYL,(1,1))
//SYSOUT   DD SYSOUT=*
/*
//COPY38   EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSIN    DD DUMMY
//SYSUT1   DD DSN=LORINCE.FIFTY01,DISP=SHR
//         DD DSN=LORINCE.FIFTY02,DISP=SHR
//         DD DSN=LORINCE.FIFTY03,DISP=SHR
//         DD DSN=LORINCE.FIFTY04,DISP=SHR
//         DD DSN=LORINCE.FIFTY05,DISP=SHR
//*           DCB=(RECFM=FB,LRECL=50,BLKSIZE=0)
//SYSUT2   DD DSN=LORINCE.FIFTY.A0811,DISP=(NEW,CATLG,DELETE),
//            UNIT=SYSDA,SPACE=(CYL,(1,1)),
//            DCB=(RECFM=FB,LRECL=50,BLKSIZE=0)
