The following document contains a considerable amount of technical information on how an ESL developer can set, track and make efficient use of memory. Unless your applications are running out of memory, or you have a very restricted memory within the workstations, it is recommended that you leave the following settings to there default values:
Setting Name |
Default Value |
Command Line Option |
Purpose |
Comment |
PRGSIZE |
512KB |
-m |
Sets the initial size of the main memory pool used by the ESL application |
Not implemented before version 5.46 |
PRGMAX |
32MB |
Not Available |
Sets the maximum available to the main memory pool. |
An error will occur if your application attempts to exceed this value and the application will be terminated. If less than PRGSIZE, then the value for PRGSIZE will be used. |
MEMINCR |
64KB |
Not Available |
The amount of additional memory added each time ESL needs to obtain more memory from the operating system. |
Prior to version 5.46 this was also the setting for the initial memory pool size. |
GLBSIZE |
128KB |
-g |
Sets the initial size of the shared memory pool used by all ESL application that are “chained” together using the “change to program” statement. |
Not implemented before version 5.46 |
GLBMAX |
32MB |
Not Available |
Sets the maximum available to the shared memory pool. |
An error will occur if your application attempts to exceed this value and the application will be terminated. If less than GLBSIZE, then the value for GLBSIZE will be used. |
