'''Virtual Storage Personal Computing''' (VSPC) was a service offered by [[IBM]] in the late 1970s and early 1980s.<ref>In Germany, the service was announced in October, 1979 according to [httphttps://www.computerwoche.de/heftarchiv/1979/42a/virtual-storage-personal-computing-vspc-mit-benutzersprache-as-neuer-dfv-service-der-ibm-rechenzentren,1194110/ an article in Computerwoche dated 1979-10-19].</ref> From a data terminal, users could run both [[interactive]] processes and [[batch job]]s on remote computing hardware (located in IBM service centres) to which they were connected e.g. by telephone lines using [[modem]]s. Among the [[programming language]]s offered were VSPC variants of [[BASIC]], [[FORTRAN]], [[APL (programming language)|APL]] and [[PL/I]]. VSPC became obsolete following the invention of the [[Personal Computer]] as computing power became available to the individual user locally.

In a campus setting, VSPC offered users the ability to create and submit programs to an IBM (or compatible) mainframe without using punched cards, though the programs were still submitted as card images, and programs so submitted needed all the usual IBM [[Job Control Language]] (JCL) statements to access the mainframe batch submission and resource allocation processes. Output from a job submitted through VSPC could be routed to a printer, or back to the user's VSPC account, though in general the output would be too wide to easily view on a VSPC terminal.
