GASP (simulation language)

From Wikipedia, the free encyclopedia

GASP, GASP II and GASP IV are FORTRAN-based simulation languages.[1] GASP stands for General Activity Simulation Program.[2]

SLAM (Simulation Language for Analogue Modelling) is a simulation language based on Fortran and GASP.[3]

GASP[edit]

Work on the original GASP project was done by Philip J. Kiviat at U.S. Steel Corporation, and was gearedto use on small to medium size computers with FORTRAN II compilers.[4] : p. 3 

Like SIMSCRIPT (conceived in 1962), there are developmental links of GASP (1964) at RAND Corporation.[2]

While one of the RAND principals conceded that "GASP cannot compete with SIMSCRIPT" the same person praised GASP's strength: that it "serves well those who have only a small machine or who use several computers with no common language."[2][5]

GASP II[edit]

While GASP II is an extension of GASP[6] which even supports PERT simulations,[4] : p. 41  a version named Basic GASP II was introduced to facilitate reduced per-user computer resources in a teaching environment.[4]

Pritsker and Kiviat "decided not to rewrite GASP in FORTRAN IV"[4] to retain support for both small and newer/larger[7]

GASP IV[edit]

'GASP IV was a further extension.[8][9][10]
